If you can get to Gypsum Valley Friday night and launch there is a great camp at 65.5 on river left but it will probably be taken but you never know. To answer you question about how many hours, it's 35 miles total so probably 10-12 hours, if you get the 2000cfs they are talking about it will easy peazy, the hard part will be finding a camp with all the people, Start early and get to camp early is the golden rule, maybe we will see you down there although I won't be there until May 11. Enjoy
