Nick, Alex and Joe:
Thanks for allowing me to come along, but I think we are heading to Browns if the flows don't drop much more.
Do what you want, but if I ever go back I would plan on making a handful of laps on Shoshone before continuing down to Glenwood. Shoshone is fun but it is over in a blink, and the Grizzly Creek to Glenwood section blows, though it wouldn't be a bad cool down for the end of the day. There is a bike trail where you can be back at your car within 5-10 min to run shuttle from the Shoshone take-out. Just my thoughts, but either way you'll have fun.
I will be heading back up to run the Chutes and Waterton on Thursday if anybody is interested. Have fun and be safe.
