Hey Mike,
Nice to hear from you again. Kind-of wondered if you were still around.
The 100 club is 50-50 for getting out of tickets. My Brother in law has had a cop flat out ask him, did you buy that sticker, when he answered yes, the cop said thanks for supporting us have a nice evening.
Me on the other hand, middle of the week, 3 am, sober, no traffic and yep! I still got the ticket.
Oh and yes it's a regional thing.
Supporting the local police is always a good idea. If you are purchasing a new sticker each year, and plan on doing so for many more years they offer a life time membership for about a thousand bucks and send you a new sticker every year. (they will send you one for as many cars as you have so you can put one on each)
