Re: First steelhead experience
Paavo, welcome! Greg is right, Chagrin River Outfitters is a great place with some very knowledgable guides! The Buffalo area is surrounded by many nice waters with a lot of options (pocket water, long swinging runs, nymphing water, everything in between). Especially this time of year with the Great Lakes creeks being lower and clear, Scandi will be just fine. You don't need to be pitching big and heavy flies right now, as the fish have been finicky at best.
The problem with Thanksgiving weekend is that many people go fishing with their family. It usually ends up pretty busy, with students home from university fishing with their family members and friends. There are fish from now and well into the new year.
As far as a guide goes, a guide the first day isn't a bad choice. If you're coming to the Buffalo area, and don't want to get a guide, I'll happily go fishing with you! I'm no guide, but I love sharing the water with like-minded people, and I find fish from time to time.
And while Greg and I are partial to lake-run fish, don't forget about their relatives from the West Coast that actually see the salt! If you get the opportunity, head out to the Olympic Peninsula in Washington. Winter steelhead are not easy to come by, but I've been obsessed ever since I first soaked a fly out there. Our fish are still plenty of fun, but the views there are amazing on top of the fish being incredible.
Hope this helps!
Working out a way to convince my university to allow me to hold my TA office hours on the nearby creek...
