Dang, I thought you went out to Holbrook after your post on FishExplorer!
Actually, there are some really nice sized SWA around. Holbrook would have prolly done you fine. It is decnt sized too.
Along the platte there are tons, and many of them are 2-4 miles long and a good mile or two wide in some areas. TONS of cottonwoods and brush! I actually saw a few squirrel on Friday at Cottonwood SWA. That is good area to start. Other SWAs within a mile or two are Jean K Pool, Brush & Elliot so right there you are looking at over 10 miles of riverbottom I would bet!
