Tell me about it, nothing beats that feeling.

Man, xena's point about water is huge... it's never just about the dirt under the feet. Water moves sideways, you know? I've seen a setup on bone-dry clay that turned to soup three feet over because of a buried utility trench backfilled with sand. That sand acted like a pipe for rain a whole block away. The mat didn't just spread weight, it bridged that weak spot we couldn't even see. That extra hour feels long until you need a week to pull a crane out of a hole.
