About three months ago I purchased 2 sheets of black HDPE, dimensions were 1/4" x 29" x40". I cut them down to 9" wide, 40" long (or right around there) for a box.
I'm no longer going to be using the sheets, probably practiced out back 3-4 times, so they're barely used. There are 4-6 screw holes in each. One in each corner and two in the middle. The holes were drilled with a countersink bit, so you should have no problem just screwing the sheets back down onto a box.
Anyway, I thought about just tossing them or selling them on ebay - but I can't imagine them going for much, so if anyone wants them, e-mail me at NolanVW@gmail.com and let me know when you'll be at Blue. We can try and work out a time to meet in the lot and you can just have them.
I'm probably going to be up at Blue this Sunday 16th at night and some weeknights next week. Or, I live in the Easton area, so if someone lives close, we could just meet somewhere too.
