So far, I've only camped in Camp Driveway where bugs are not an issue. However, I've noticed a number of spots where velcro and flaps don't close completely. In addition, the mesh on the new PUP will not be small enough to stop those little tiny black ones that bite like the devil (we call them "no see 'ems in Nova Scotia). Not much I can do about the screens, but there are spots where blackflies and mosquitos can get in. Is there any way to seal that up or is it an issue?
