I got a letter in the mail from the dnr It was the smoking tail pipe program. One I own a diesel they smoke two I guess my truck some how apeared in Des Moines (on 8/24/04) while I was on trucking on the road. I understand it is a good program but I shouldn't get more junk mail for what is unavoidable and that I wasn't even responsible for. Plus I think its a waste of tax dollars.
