Hey Starleen2
My EZ Up from Gander Mountain sporting goods comes with tie-off lines at each corner of the top. The five gallon buckets have handles and I tie the tie-off lines to the bucket handles. The first link is at Petite Jean II gathering.
Photos by Dave. My TD is the green one with the EZ Up and mosquito netting. You can see the lines attached to the bucket handles. Last summer we were camping and the fire at the site next to us got out of the ring. Just untied one bucket and doused the fire!

The second picture is from Matagorda Bay. Pics again by Dave. It is harder to see the buckets but you can see how hard the wind was blowing. My attached side panel is really billowing. The buckets are easy to transport empty. You can go to just about any store that has a deli or bakery and get their empty pickle buckets or icing buckets.
