Pick up a styrofoam cooler for $4 and a case of h2o, you can also buy ice.
Over in HBC they have a coffee, corn on the cob and ice hut (yep!) where you also can leave your pad or phone for a charge.
DON'T forget the shower shoes! Groady is a good word for the showers, I had to shower in my street shoes and try to dry them each night since I didn't bring my flippers.
Be prepared for wet. A tent with rain fly would be a good idea, tie it down good also.
The vendor breakfasts arnt too bad, around $8 maybe. I skip lunch.
There is usually some sort of dinner going on depending on any groups you may be associated with. Canardians have a speggetti feed Tuesday, a banquet on Fri for example. The RV guys have some events of their own, Bonazas etc etc.
Getting into town for a resturaunt is no big deal, takes maybe 1/2 hour each way.
There is free wireless there but I could seldom get it to work from my camp site, enough to get mail, little else.
Have fun, see you there!
