Good luck finding a used cover that isnt already toast.
A new fitted canvas cover is expensive, but the payback is better than having to shrink wrap every year, and ecologically more sound. (Just my personal opinion).
I had a winter cover in Northern Michigan that made it through nine years of snowy winters with minimal maintenance.
If you do buy a fitted cover, specify Tenara thread. Expensive but worth it.The seams are always the first thing to deteriorate
I didn't answer the original question because I am not,familiar with Staten Island.
