Zeke/Milt was posting up until last year but seemed kind of agitated in a few of his last replies. Think he was tired of people dismissing or not reading his posts and left for a while. Seemed like an ok guy who liked to share his experience with others but was just burned out.
Burnin' oil hasn't posted on here for a while. I enjoyed his quick wit and his posts in ot were generally good natured and funny.
