I live by a river...think: sandbox. I use 30"x3/8" rebar pins that I buy at the local lumberyard. Drive them in 'till your lawnmower will clear and put some flagging tape on them so you can find them, and you're done.

If you want to pull them out, a prussic loop and a long pole for leverage usually does the trick. If not, drive 'em flush, and walk away...they're cheap.
