yeah - I had an exhaust brake (Pakbrake) on my '97 Dodge automatic - had to cobble together a trans lockup system that I wasn't completely happy with, and am now itching to put one on my '07 Dodge manual trans. ... But fun things like Front Sight have distracted me, as well :)
I've done multiple handgun (also a 1911 guy) and rifle courses, probably going to do the shotgun course next time out, but also considering the Precision Rifle course(s).
We take anywhere from 5-10 people out once a year from our classes we used to teach (got out of teaching last year). Sort of a bonus "field trip".
to bookend this back to the original topic - PacBrake still the best exhaust brake system out there for my 07 Dodge/Cummins? :)
