I just had a call from a salesman from a Chrysler/Jeep dealer, and when I told him I was waiting for my Tread Lightly membership certificate, he did not know anything about TL. I have been referred to him by more than one person, and I understand he has been selling there for 18 years. Is he being honest with me, or don't many use that program? Have I wasted my $$ joining TL? I'm too far from Chicago to buy from Pat!!
