Reminder:

·         Line Judge – 1 person

·         Runners – 4 person

Venue 

ISR Gymnasium – This gives us more space for the larger number of participants we expect to have this year.

 

Track Access

Track access to test, tune or play with cars will not be allowed….not the night before, and not on race day.  Please help us ensure the track stays smooth and straight by keeping the kids at a safe viewing distance. 

 

Graphite

The Race Committee cannot find graphite to provide for the racers.  Graphite or other dry lubricant is allowed before inspection and weigh-in.  If anyone has graphite and in the spirit of fair play would like to share, please do.
