during the tybee I used two infusion sites, both covered with tega-derm (think of shrink wrap for your skin) and didn't have any problems.
There are ways of keeping it dry but I've found that water will go where it wants, and the body can build up moisture from the inside if trapped.
As for that beer, I severed relations with my client in Waltham due to them being an unprofitable venture. So I don't know when I'll make a return to the area unfortunately <img src="http://www.catsailor.com/forums/images/graemlins/frown.gif" alt="" />
