Skip, call Sunoco directly and they will give you a distributor list in your area. I did this and found a guy about 45 minutes from me.
How much ya need? I burn this fuel in the GSXRCAR, probably have 5 gallons in the fuel cell and jug in trailer. I'm in Roswell.
http://www.racegas.com/fuelfinder I've used this on the road to tracks with success. It shows what fuels are available where and usually gives good info as far as hours, phone numbers and web sites.
OK.. here is an FYI... not sure about other fuels, and the 260 stuff is great.. but it does NOT like the sun - UV.. do NOT store it in those plastic (semi clear) jugs.. unless you have a blanket of sorts over it... it will go bad due to that UV.. but will last a very long time if you keep in covered or in a metal container...
Claysburg...sorta by Breezewood, PA. You gotta call Sunoco and they can narrow down the search for you instead of calling everywhere. I'll probably bring a 5 gallon can home from Road Atl to have just in case.
