scrap of Tyvek building wrap (Cary NC)

I am looking for builder or homeowner that may have a small scrap piece of tyvek or similar building wrap material I can use for my two person tent footprint. It only needs to be about 5' x 8' approx. in size. I really would prefer not to buy an entire roll. I will pick it up. Cary/Morrisville location. Thanks.
