A motorcycle centered group in the MD/VA area mainly known for: their willingness to give frank opinions without concern of possible hurt feelings, their ability to ride extremely technical back roads at a high rate of speed and their ever growing presence at local racetracks. Many feel the meaning of TPG is secret, but in reality most people just don't ever ask. Originally given the name "The Problem Group" as an insult by one such person who was offended by the group's open criticism, the name has since been adopted and the group has since grown significantly both in number and ability.
Damn, I tried to keep up on that TPG ride and totalled my bike.
