Glad this thread got bumped to remind me to comment on this one. I've been trading DVD's with Bill for several years now every fall, and while every DVD is definitely worth the watch, his 2010 production takes the cake out of any that he's put together in my opinion. Both because of the incredible year that Bill and family had this spring and summer, but because as Adam said the at times humorous and overall fun to watch moments that he always seems to document so well.
The August Minnesota EF4 tornado was certainly the highlight for me, but even on what could be considered a "down day" for Bill in 2010 was full of beautiful skies. When I sit down to watch storm chaser DVD's, I have a habit of fast forwarding a lot to get to the "action shots", but I never once hit the fast forward on this DVD, and in fact ended up re-watching a lot of it a couple days later.
