I just bought one in November myself..and it's been the best investment ever...Aside from being a neverending bottomless pit to throw money into lol.
I took it out on a lake to get a feel for how it handles, but, this doesn't really prepare you for the river much...at all. It's a whole different beast in the current, and in a good way. They're perfectly designed for river use.
I went out with someone that knew what they were doing the first couple of trips, and they weren't fishing trips, I was 100% focussed on getting a feel for the boat, and that's really the best thing you can do. Find someone that A) can row a boat and B) knows the water you're going to be learning on. Make sure you have spare oars and oar locks, and a solid anchor system. I quickly learned that a little 20 pounder doesn't cut it, and a bow anchor is a must have, it gets ugly quick when you're anchor doesn't hold. Not sure where you're from but I learned on the McKenzie, Willamette, Umpqua, Siuslaw, and Alsea this winter. (I don't recommend the umpqua as your 2nd trip on the sticks...) They all offer somethin' different, and the Siuslaw and Alsea are cake, though those runs are over now.
