If your getting free bikes (which a few are) & help from other sponsors you can make a good chunk to supplement your normal gig... Not paying Vets will deff hurt turnout.
What's the Best "bang for your buck"
1- the most track time per day on a so so practice track ?
2- having a perfectly prepped , safe & awesome track layout on Raceday ?
3- Awesome Series awards ??
4-longer Motos ?
5 - what else ??
For me it's # 2. I'd much rather ride a track like Pagoda or Miles which are Mint 90% of the time. (No disrespect to my other Fav's Ramblers , E-Ville & DG.)
Ride practice Sat Race 2 classes Sunday & watch some great racing when I'm not out there.
