P M, Get yourself a Cabelas catalog or go online to Cabelasdot com for startup outfits. Or check out the sponsors pages here on FAOL. You don't have to spend a fortune to flyfish. Not immediatly anyway.
Also, since you are a disabled vet, try finding a local or nearby Project Healing Waters chapter or something similar. Also a local fly fishing club can help you get started. The Washington Fly Fishing Club has a PHW chapter from Madigan Army Hospital.
Good luck to you. I hope this helps. Jim
