I will leave when I no longer have access to a computer PERMANENTLY. (Read:death, acts of God Himself, etc)
However, there have been and will be long breaks from time to time because of school, family situations, etc. If I go into the army as an officer, then I will have about a 4 to 10 weeks without posting. So, if I'm gone for a while, don't worry, I'm just dealing with Life. If I'm gone for more than 1 year, then worry.
When driving a Classic Mopar, be sure to run over as many Geo/Chevrolet Metros as possible.
