Colorado Fall Color Along Ouray County Road 5

The fall color along Ouray County Road 5 is a local secret—not the domain of tourists—shame, they’re really missing out! Loretta and I took the trip this morning. I snapped a bunch of pics with my Pentax K100 (yes, raw) and put together this short video to showcase the results. And what’s amazing? Here it is October 14th, and the leaves are still on the trees! All it’ll take is one good windstorm and we’ll be headed into winter. By the way, the video is best if you watch it full screen at 1080p.

The music is from the YouTube audio library, a short piece called “Swamp Stomp” by Silent Partner.

My new book, The Berki Blunder, is now available on Amazon

You know me: I do travel videos and ham radio training videos and I like to have fun. And I had fun writing The Berki Blunder, a short science fiction book written largely from the aliens’ point of view. You can get a kick out of it too!

The Berki Blunder, by Dave Casler, now available on Amazon and via the Mt. Sneffels Press Fantasy Catalog

The Berki Blunder, by Dave Casler, now available on Amazon and via the Mt. Sneffels Press Fantasy Catalog

The Berki Blunder is now available two ways: via the Mt. Sneffels Press Fantasy Catalog, and directly from Amazon.

An alien ship, in trouble, lands on Hollywood Boulevard. Bad enough? And it’s the day of the big premier of the SciFi movie Asteroid, so they land amid huge crowds. It gets worse… One of the crew members is lost trying to find a bathroom. Two earthlings who help replace the broken motivators won’t leave the ship. And the U. S. Air Force has them surrounded. What are the poor Berki to do?

The Berki are aliens. We’ve heard everything about aliens, right?—how they’re so advanced they’ll order us around, or so cute we want to cuddle them, or so evil they’ll destroy us. But what if they’ve figured out interstellar travel, but not much else? The earth would certainly seem mysterious: advanced cities, cell phones, and blockbuster movies. And this strange thing called the Internet, which they fear is a form of magic they’ll be unable to duplicate. So they fly around and gather what information they can. And maybe look for a lost comrade while they’re at it. That is, as long as their spacecraft works properly. They’re on the Periwinkle, a Maginator-class spacecraft, a class not known for its reliability. Welcome aboard!

Colorado Color 2014: Goliath Won (Poor David)

Poor David (that’s me). I put the pebble right smack on Goliath’s (YouTube’s) forehead, but Goliath just laughed and did what he (they) wanted to do anyway. So…. I’m trying this again. I put this video up on YouTube last week. I used music called “Tree Hop,” obtained via SmartSound (and yes, I do have the rights to use the music royalty free). Well, YouTube said the music was actually from Getty Images (of all people). I appealed, but there’s not much point in fighting Goliath, even if my given name is David. Anyway, after my appeal was ignored, I deleted the disputed video. I went, hat in hand, to YouTube’s free music library (and I hate to admit it, but it’s pretty good), and picked out a piece by Silent Partner called “Yard Sale.” Anyway, here’s the updated video.

For those interested, “Tree Hop” really is available from SmartSound. Click here to see it and even play part of it. The cool thing about SmartSound is that I can tell their software, SonicFire Pro, exactly how long I want the music to be, and it’ll make an audio clip that long, complete with a proper beginning and end. Further, I can decide just which instruments I want to keep and which to turn off (for example, to create simpler music under dialog). Alas, compared to YouTube, they’re also a David. Their help page regarding YouTube disputed ownership simply suggests I use Vimeo.

Vimeo is a nice service (and I’m even a member), but frankly YouTube is where it’s at if I want a real audience. Hmmm…maybe I’ll put the original video up on Vimeo. SmartSound says Vimeo is a partner and won’t erroneously tag its music as a copyright violation. We’ll see. (Added later: I did put it on Vimeo. Click here.)

Track Maintenance Vehicle for D&SNGRR in Silverton, Colorado

Track maintenance vehicle on Durango and Silverton Narrow Gauge Railroad. Silverton, Colorado. Little one-man vehicle that had to be manhandled off the track onto the side track.

Video taken on Wednesday, 24 Sept 2014, in Silverton, Colorado. I used my iPhone 5S and did the post-production in CyberLink PowerDirector 12.
