Years ago I went to a multi day auto race with friends and some older friends of those friends in an RV. There was like a half mile long line of RVs and vehicles at the gate and everyone wanted to get in early to get a good spot. When the gate opened these guys drove up past the whole line and next to the gate. Then one of the guys donned a day-glo vest, got out, walked around the RV, got in front of next RV in the line and held up his hand, then waved the rest of us through the gate. After we were through he waved the next vehicle on and caught up with us a bit later.
