many race tracks, demo Derby’s mud bogs, and such don’t have concessions in the pits.  Motorcycle rallies and get together.  Poker runs not at the start but at the stop where they will be around 11 to 12. then go back to the finish line.

don’t spend big money on an event if you have only a cart.
don’t pay for lists, most are BS when it comes to numbers.

The lists are free all over the net, get the name and number of the town and county Chamber and the police dept.  find out the info free from the chamber, then verify the numbers with the police dept.  Tractor, and lawn mower pulls, mud bogs, small rodeos, church events, are all usually good, at stadium events like rodeos work the bleachers like at a big league ball Park.

stay away from fair midways till you’re ready, try VFW, American Legion, call churches, and look for other small music events.  they are often over looked.
