I would suggest you put a gate (sure, there is the cost).

Most bikers and hikers will be there on the weekends. The post office
does not deliver mail on Sundays, so no problem with a gate on Sundays.
You will likely know the approximate time of mail deliveries on
Saturdays, so stake it out and open the gate for the mail carrier. Once
delivered, you can leave the gate closed.

These are good ideas, and we've thought of a few others over the past few
days as neighbors wandered by our local roadblock:

1. Put up a gate, with good signs, but leave it open.
2. Same as above, but make it a proximity open.
3. Make it open at the time the post office arrives.
4. Put *one* mailbox outside the gate and have it open whenever *that*
mailbox is opened (and stay open for, say, 1/2 hour to allow egress)
5. Close the gate only on Sundays
etc.

Everything really hinges on the post office who won't do gate codes.
