You may want to check out either the Pikes Peak River Runners Group or the High Country River Rafters websites. I don't know if they have the capability to post videos like that though. Try sending an email to the groups webmasters.
Oh Yeah, another place would be the Be The Pig website - http://www.bethepig.com/
Brad's still working out some bugs but he may have capability to post videos.
Looking forward to seeing this stuff!
