Thanks, the overhead brace is in 2 pieces and the distance between uprights is 10 ft. just like in Risk's plans. The Kelty tarp is a 9X9 which makes the diagonal close to 13 ft. I've since made an 11 ft. ridge McCat style tarp (8 ft. wide) out of silver DWR which is in my avatar and some pics in my photos on this site. I've got the material to make a 12 ft. ridge X 10 ft. wide Black McCat out of sil as soon as I can get around to it.
