Ha. I wish there was a 20'er in Browns....
Shonuff, IMO Browns becomes class IV somewhere around 2500 cfs. If that's the case you might want to think about Rincon, Texas Creek to Pinnacle Rock, or Lower Browns with a portage of Seidels Suckhole for a warm-up.
Make sure you give me a week or two heads up, that way I can arrange a little free time from work.
