I'm headed for the beach vacation in a few weeks. It's a rather remote area where we drive out water's edge, I was thinking I might throw up my Mac Cat in porch mode for my wife as she really can't tolerate a great deal of direct sun.

Here's my thought, to find something I can attach my guylines to that I can burry in the sand as an anchor. I was thinking of something like a round plastic lid of some sort.

My wife is looking at beach shelters that are on late season sale but they seem a bit small for the money. I'll be experimenting in the the yard with some salvaged tent poles but the sand dynamics are something I can't really test for. If anyone has any sand experience they could share. Also is it necessary to put a base under tent poles?
