Every spring one of the fun trips is an overnight kayak float trip down the Brazos river below Possum Kingdom Lake. Everyone loads their kayak up with their camping/fishing gear and food/water and does an overnight float down the Brazos river. Here are some shots from my trip a few years ago.
Sunrise and the morning mist on the river.
Very nice.
At the end of May, I am invited to take part in rafting along the river on rafts, with a total length of about 320km (this is about 200 miles, as I understand it), until I decided to agree or not =)
You should do it, unless you just hate that kind of stuff, sounds like it would be a blast.
In general, I like such adventures, especially given that I now have a sedentary job, for me it would be useful. The only thing that bothers me is the possible bites of insects, because I'm allergic to them.
