After the drenching we got @ Everybus last year, and the fact we have a third member of the family now, I've been thinking about making a tent fly for the pop top. When purchasing the new (new! It works!) speedo from GoWesty, we noticed they've already done it.

Installed it today with good success. Looks like it will keep the majority of the water off the canvas, which is what we're after. It should also insulate a little in the cold.
