There was a vendor at the rally I'm trying to find. They had a trailer/booth in the back parking lot and sold Nolan Helmets (among other things). I cannot remember their name. I have tried unsuccessfully to find a Rally vendor list on the MOA site. If anyone has any guesses (or better still, a vendor space floor plan) please let me know. They sell an adapter to allow Nolan helmets to be used with normal helmet locks. I meant to pick one up before I left, but didn't make it back over.
