For those flying to Oshkosh, here is a tip. Along with the mandatory tie-down, consider something for under your tires. Just a piece of plywood about the size of a large shoe box cover should be enough to spread the weight over the grass. If you don't do something, you may sink a bit into the grass, and when you try to leave it will be either a hard tug on the tow bar, or a high power run-up just to move. My...uh...friend had this issue one year, and learned for the next time. Fly safe all, and see you there.
