Darnell, 4-5 years ago the MTQRL paid to have an ambulance at a few of their races and it was nowhere near the 800-900 you stated. Possibly because we only needed one onsite for approx. 4 hours to cover all of our on track activity.

I believe what you stated was true for your event, but didn't want that number to prohibit someone from checking on an ambulance for their event.
