I will be attending Lil Tally the weekend of 4/20 for my first race. Can I just show up and complete all paperwork/registration that day or is there anything I need to do before I show up? I am aware I will need to take the racers school but as far as paperwork is concerned what exactly do I need to do? Also, I have been racing all my life (sprint cars) and would like to keep my number (96). Is this possible or does WERA provide my number? Thanks in advance!
