Thanks to all of the food trucks who were here Tuesday night for our first Food Truck Night and special thanks to everyone who supported the Trinity Parent Organization and the Booster Club. Each truck donated 10% of their sales so valuable funds were raised for both the TPO and the Booster Club. Photos from the night can be viewed on Facebook and Twitter by clicking on the icons above.
