Drover's in WV

The Blue Danube in Toronto, OH (not sure if they're open any more - only served on Sunday and Thursday)
Anchor Bar are OK, the two above are much better both in terms of size of wing, crispyness/juicyness balance, and taste of sauce.
Quaker Steak and Lube are OK. Louisiana Lickers are pretty darn good. Probably the best of the "chain" places.
BW3 has great sauces, but the chicken itself is horrible. Tiny midget wings.
To the poster above, sorry, you can not find a good wing, period, in Colorado. Steamboat Smokehouse in Steamboat Springs is the only possible exception. You have to experience what it's like in the area between say Pittsburgh and Buffalo - there's a TON of great wing places in that part of the country.
