We were once driving round Iceland (the country) in a Freelander with a trailer tent. The campsite was full on the evening of the National Day: it's a local tradition to camp with crates of beer on that day. A storm blew up. I've never seen so many tents rolling across a field, chased by, and possibly containing, inebriated Vikings. Our awning detached from its frame. My daughter climbed on the tent roof, and reattached the awning with Micropore medical paper tape: the stuff you use with people who are allergic to plasters. It lasted another week driving round the North of Iceland!
She's now a nurse, and uses the tape for what it's intended. Duct tape's little brother.
