The only skewer issue I've ever had was when fixing a flat, I lost the nut in a forest of leaves. Made it to a hardware store in the next town, sans skewer, and found a replacement nut that sufficed until I got to a bike shop a couple days later.

Discovered that a skewer is not absolutely required, as long as the road is smooth and you ride very carefully. It's only purpose is to tension the fork against the hub to keep the wheel from coming off when you hit a bump.

Point: Don't lose the skewer nut.
