Don't we have enough restaurants in Folsom without needing to go to a food truck?
Food trucks are fine, but don't they normally go around to work areas that are not close to places to eat.
I think we've already concluded in other threads that the dining scene in Folsom is pretty weak. Once you exclude the mediocre chains, you are left with a handful of non-chain places, of which a small percentage are actually above average in quality, service and value. Especially when you narrow it down to the non-sit down "fast food" type places that the trucks are really competing with.
Either way, they provide convenient variety on occasion.
Besides, that same logic could be used against things like all the farmer's markets in town (we have enough grocery stores) and the Sutter St crap fairs (we have enough stores selling trinket crap).
