I ordered a silnylon guide tarp (sour apple green) late on a Friday night and the following Friday it was delivered to my home. I was very excited I grabbed my new tarp and the kids and headed to the in laws for the weekend. I started to set the hammock and tarp up in the in laws backyard glad to have avoided a cramped night in their small spare bed with the wife and two dogs. Here is where things get weird the tarp tie down points on the long side are not space out at regular intervals. Along the long 390cm side the grommets are at 96 cm and 230 cm from one side. There is also a center tie out in the middle of the tarp that is inline with the 230 cm edge tie out. This leaves it at approx 230 from one side and 160 from the other side. Has anyone else bought one of these tarps and are the dimensions similar? When i called the local MEC they said that the tarp they had was also not regularly spaced. On Thursday I plan on going in to see about exchanging it, if the one they have isn't better should i just return it.
