are trampolines water proof?

well, the neighbor had lights off, both cars gone, no toys in the yard and the trampoline mat missing. Nothing but the frame.

I gave this a small chance that they had moved, since they are tenants.
They have not moved, as it turned out.

I guess it is easy for them to remove the mat and fold it up and only use it periodically, though I see the kids play on it quite often.

I assume, now, they take it off when not in use.

Probably a good prophylaxis against lawsuits by neighbors using it.  :)

I found it unusual that it was gone, as was the people, dog, toys, lights.
But, despite the area hoping they had moved, they have not.

How hard, or easy, is it to remove the thing, and fold it up, etc.
How much does it weigh?

With good weather here, and the kids play on it so often, I was just surprised to see nothing but the frame.

thanks
