Chris,

Tell them to build everything out of fiberglass in the shape of an egg. Big, small, large, tall....whatever....it's the incredible durable egg. One could have an egg shaped house, put in a hammock with a safety belt and you'd be good for just about anything.

Oh and don't forget CPH20 who'll deliver the drinks and snacks. When one is saying WhooHoo what a ride, they'll really be doing it in style. Humm a aqua colored egg house...I like it.
