Looks awesome. I'd like some of that color...I have quite a bit of 1.1oz DWR and 1.9 oz untreated in that color, but the only sil I've seen is a small sample-sized square. If I had some, first I'd get a tarp like you did. Then either a blackbishop sack or a summer hoodless poncho (definitely not a hunting-season hoodless poncho... ).
Been planning a hoodless poncho from the gray sil I have, though.
Looking forward to seeing that tarp at Mt Rogers. If you wake up and it's gone, blame Grizz and Finn. Can't trust those guys with double-identical-consonants at the ends of their names.
