ACE Hardware FTW

So, your post-apocalyptic postal LLV has fallen off a broken bridge on the south end of Upper Matecumbe Key in the Florida Keys. You need to get to Key West despite all the islands between your present location and Ohio Key are washed out. That's 41 miles of swimming, walking on sand bars, or magically ascending to the remaining bridges.

Considering the journey has swims of up to seven miles, my guys needed some floatation device. So, I asked in the sci-fi forum at Absolute Write. I let them know that all vegitation and 99% of all animals died two years ago. My first response was "Lumber."

Lumber? To prove him wrong I searched the area in Google Maps for lumber, and wouldn't you know. They passed an ACE Hardware less than a mile from their crash site. Though, of course, all lumber and useful supplies will be gone.

One main character says the foam sheets they put on buildings when they're being built would have been perfect. Female MC asks what it's used for. Male then says, "I guess to keep the rain out." She says, "So they take it off before they put the rest on?" Since the answer is no, they bust through the wall and get some kickboards out of it.

They also need a bucket to catch rain in. They'll take a paint can and pour out the paint.
