Hmmm......ok, so I guess the answer is no lol. I was just talking straight up outside on the patio, but yea the 100 degree summers will kill them, as well as the moisture. Was just wandering if anyone tried it. Can't get a shed cause it's a apartment patio and don't want to pay for storage for just a few boxes. I tried flattening and separating the styro and storing that, but with the bigger pieces, doesn't make a big difference. Will have to try and sneak them into my parents attic lol.
