You put them on all four posts. Around here we put sand bags on them. 30 pounds or so.

You put them on all four posts.

Yes. Four missiles. We get serious winds here, a lot. Anything not anchored firmly will wind up in Texas, or Oklahoma.

[Vermont Lt]

The tents actually have a vent on the top so they won’t blow away. Again, 30 pound sand bags on each leg will do the trick.

We get winds here in New England too. They are called hurricanes.

Home Depot sells a set of four 5-pound weights for canopies. Around $35.
