This fall while taking a Harley trip down to Granby CO we decided to white water kayak. It was awesome, outside of the wet suit being a real hindrance on the ability to breath in the upright position, nothing light about that
There is some super fun rafting to be had out in Western MT, by Flathead Lake. Go in late summer, and no wetsuit needed. Much fun!
Yep, took the kids on a trip down the Middle Fork of the Flathead. Good times.
