I bought this tarp a couple years ago but a shoulder and another spinal surgery has dashed my hopes of ever dipping a paddle in the BWCA again. I have never used this tarp outdoors but did have it set up in my classroom for a week for an activity. I seem sealed both sides and have it rigged with zing-it and some bling from dutchware attached to the ridge-line stuff sack. I am looking to get $150. Tarp is green in color. Let me know if you have any questions.
