I'm feeling a bit of shock & awe here. Hell, give the guy his $50 back and hope there are no hard feelings. R Gruppe is simply not an "organized" club...no real officers other than Cris, no monthly newsletters, just gatherings of guys who appreciate the early 911 and it's "sports purpose" roots. If it's newsletters & stickers you need? Yep, there are other clubs. R GRuppe's "newsletter" is actually an annual of sorts, usually sent out after the main event of the year, a gathering on the California coast...
