The trick to anchoring one is to bury the legs 1-2' and then use a mobile home tie down auger and screw it in the ground directly below the stand. Then attach some wire cable to the base with a turnbuckle attached to the mobile home tie down.
Get the wire cable tight and then tighten up on the turnbuckle. After a good rain comes through makes sure to go back and re-cinch it up.
This trick has worked great for us so far.
This is with steel framed stands and bases BTW. I don't see why it wouldn't work with a wood base, just don't go crazy on the turnbuckle
