Thanks for the comments - I'll pass them on.
@vert. I'd like to take some of the credit, but I haven't taught him all that much in all the years we've been flying. (more like the other way around). I do get credit for funding our hobby/obsession and getting us out there flying, however!

It's a fun way to spend time together - I've always got a potential flying partner. We plan on working on pair flying, but haven't moved too much in that direction yet.
@Nancy. Thx for the vote of confidence - it's what I always tell my kids.
I also don't understand why some videos play on phones and some do not. I don't do anything differently when I upload them, it's just that some get a different syndication setting that others. I suspect that the music is what determines this - some must not be allowed to play on mobile devices, although I thought that vimeo just played everything.
