Hi,
The FB group is much more active than the group here on C5:

I'm not sure about the registered MT plates. They do require front plates in WA so I'm assuming it doesn't matter where the car is registered, they'll still ticket you without one. Unfortunately it happens a fair amount to Camaro owners around here (and maybe all cars for that matter)
