It varies year to year. It is usually left to the local dealers to bring what they want. Little factory support. Last year there was no Fountains and no Fastecs and one left over Scarab. Some Bajas, Sunsations ... An Eliminator dealer all the way from Iowa.
There have been very few high performance parts suppliers in the past.
It is all inside and it shouldn't be too crowded on the 1st. A nice day out if it's not too far.
