I have spent most of the last 3 days roaming around in south Arkansas and it is amazing how many acres of low-lands are under water, how soggy the high-lands are and how treacherous the trails are that are along the sides of hills.
Didn’t see any snakes although snake-boots were in use and it was warm enough to get lots of ticks. 
Beware, and take care, out there.

To help you out a little with this info, *I believe* small craft warnings are issued at about 70-80,000 cfs.
Live a good, honorable life. Then when you get older and think back, you'll enjoy it a second time.
