quieting the green monster

[roccit_53 at hotmail.com (C Boyko)]

Excellent news Allyn. I just brought home my new 18" Borla, likely it'll add 
some weight, but I kinda like the idea of not going deaf. It'll be a while 
for my report on it, hope it fits.  It's supposed to snow tomorrow, so no 
Roccin' for me. Blech.
