If you stop at Rocky Moutain Adventures on the highway north of Ft. Collins where it intersects with Shields, they have a guide to the Poudre - cheap and very informative. It has the info on all the rapids. Wish I could take you this week. We leave in the morning for the East Coast to surf with my grandkids for a week. At this level, Gateway Park, a little over 2 miles upstream of Picnic Rock, is a good launch. Top of a long hill, hidden drive going down to the right (marked). City of Ft. Collins lets you launch there for free if you don't leave your car there. We drop the boats, drive back to Picnic Rock take-out and leave the car, then hitch back up. You can scout all the rapids on the way up. Screaming Left Hand Turn, the 2nd rapid (1st marked one in the book) has a big wave train, so you may want to stay a little left (inside) if you don't think you can handle it. The rest of them are no problem.
