I bet by the end of the day there would be a lot less traffic. Also, you are more likely to upset those who are in a hurry to leave, such as the early Sunday risers (who leave camp at 5am-ish) than to upset someone who wants to take their time leaving the springs Sunday afternoon.
Right before you start to head down, switch your CB on to channel 10 (the official MCR5 channel) and see if there are any rigs coming up.
