I know a lot of the GrassRoots guys very well, including John, and I can tell you it's a very well-run club with a LOT of great people. They do a lot of South Jersey runs and do have a booth this year at the York,PA Jeep Show. Try to make it out there and meet them, or at the very least, attend a run or meeting and introduce yourself. They are a welcoming bunch and you will not regret it.
