Eric, whenever i will be able to get some land. If flat'ish, i might try square, but, i don't realy need it. I bet i will go more for terraces. And as you said, may be crescent shaped, to gather a bit of water. It's dry here, but not everywhere and not always. The snow cover is thick in the winter, and melts slowly, so water seeps into the ground. Spring is usualy as wet as seatle (well, exagerating a bit) and then it turns dry mediteranean weather from may /june, till october.
Huh, by the way, if a guy with a wingsuit reaches here from the mont blanc, he'll be in the guiness book of records!
As i am 125mi further south, and 155mi from Nice, nearly mid way.
