We have a ton of space, (about 3 acres) and in addition to the house, there is a houseboat/dock with room for several boats to tie up. We have a huge fridge, big bar area, a covered pavilion for evening coctails -- hell we may not ever even hit the lake. "Camping" during the day is fine, but the property owner doesn't allow it overnight. We may have a couple of bunks open in the houseboat (it has an A/C), but its always pretty busy and serves as the boat equipment storage area and day kitchen while we're there. I'll post a map when I'm home this weekend.
As to the lake, its finally full (overfull actually), so there is plenty of room to soak up the 4th of July crowd. The cove we're on is great for skiing and boarding early -- during the day it fills up pretty fast, but there's plenty of room on the main lake and both rivers are now full (Pedernales and Colorado), so we'll be able to find nice water. Hopefully we'll get a few more Epics to show up, and we should have plenty of boats for wannabe Epic Owners to try one out!
