Race Gas program details

Each member who gets their hard card will get a $10 Rocky Mountain gift card and each racer entered at an event will get a $10 card. Muti-day events will count as one event, so with our current schedule a racer who gets their hard card and makes it to 8 events would get $90 worth of gift cards.
