Here is another welcome to FAOL from Tennessee. I have to agree that squirrel is a fantastic dubbing material. I use it 90% of the time on all my subsurface flies because it makes a very spikey body with lots of movement in the water. Please ask questions, make sure to visit the Beginner's Fly Tying section here and be prepared for a lot of fun and relaxation with fly tying and fly fishing.
As a side note, please be careful of "road kill" material. Make sure to clean it good or you could contaminate all your fly tying material with unwanted "bugs".

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
