Indy,
I thik that the only way you are going to get to the Poly from the YC is by bus...I could be wrong though...
As far as the Tonga goes...look out...good enough to be certified for a diabetic coma!!!
THe stuff is awsome, and we absolutley have to have it once when we go...on one trip we did not get there (stayed off property for the 1st and ONLY time) and you want tot talk about being depressed (not to mention hungry!).
Enjoy it with the thick cut of ham!!!
Dan
