Hey Chris...here you go...(508)-487-2100 That should be the one. But just in case this is the # to the provincelands visitors center 508-487-1256 They may not be able to tell you specifics there, but will send you in the right direction anyway. I think the # you had is for conditions and such.
I am pretty sure they sell seven days a week, or they used to anyway and the hours are I think 9:00- 3 or 4?? at least three anyway,but the may break for lunch so you might want to double check before you go.
I heard some rumors of fishies in the area so dont forget the gear!!!

But save some for me! Hee, Hee, Hee!
