well, as far as busy counties, we have one sole ambulance company in our county with 64 trucks in the fleet, we average anywhere from 10-12,000, yes THOUSAND calls a MONTH and 9-11,000 transports monthly, and thats our "slow season" before the snow birds come!! We have some down time on a 12 hour shift, but generally just enough to eat a few bites and regroup for the next call.
