THR and TFL, obviously.
I'm a big fan of diesel powered vehicles since I own two Dodge trucks with the Cummins engine, so I belong to the following forums:
VirtualDodge (Idaho Chapter member)
Diesel Power Magazine forums
Diesel Truck Resource
Diesel Bombers
Online gaming resources
I've been part of these two organizations for the better part of 8 years. Most of these guys are like brothers to me and I'm proud to know them.
USMCG.ORG - Online gaming for Marines. Obviously you need to meet the main requirements of earning the title and honorable service. Recognized by HQMC (Headquaters, Marine Corps) in its early days under a different name.
FMF-FAF.COM - Online gaming for all branches of the military, police, firefighters, first responders, etc.
