Andy........ You have run the VCA events at PIR. Solo-format.
Viper Days Challenge Series is essentially the same thing. Instructors, safety workers, ambulance standby. "Software" training in classroom before you go out. A mean-*** chief steward to keep participants in line.
Insurance hint: ALWAYS SIGN IN AS "STUDENT." Never as participant, driver, racer, etc. If records get subpoenoed (and they will in a dispute) Your MOTIVE was clearly learning. There should be no mention of entry in a TIMED EVENT or contest. Do not even put a transponder in your car. Do not enter the competitive series and keep times, except for the LEARNING TOOL they are...to see if you are smoother and therefore faster.
In my opinion, based on giving depositions in 3 claims (all won by drivers) if you WANT to compete for times/awards/prizes, you put your auto insurance at risk two ways: a)No claim; or b) claim paid and insurance cancelled.
Hint # 2 for Skip / Bruce: If this hint is used ONCE in 5 years, you will be glad you did.......... IF you do NOT keep a copy of the "PRIMARY MEDICAL INSURANCE CARD" of every student/entrant, along with any Med-Stat requirement, you should. In case of injury, it is so much simpler/faster/easier if "SOMEONE" besides the injured person has a copy of the insurance papers for prompt admit at local hospital. Most of us carry a health insurance card.....Get a copy of Drivers License and Health Ins card before allowing anyone on track. Keep in med-stats file, preferably near the ambulance.
