howdy Don, welcome to Gadgetman Land!
Colfax Wisconsin, eh? There's another Colfax in California 100 miles west of Reno Nv where I am, about 30 miles east of Sacramento on I-80.
Always glad to see someone w/ lots of experience on here, you can lend a newcomer's perspective. I've been one drawn to new/unusual technology, and I was lucky to get introduced to the Groove in person w/ Ron 3 yrs ago. As amazing as that was, I came to understand much more about the Groove and related things since then. There's been a ton of info/experiences posted here, nearly all is in the Index button at top left of the forum page. Also- Ron's Gadgetmanglobal and Groovy Service Bulletins, 2 different youtube channels.
Please do share your experiences w/ the Groove here, pics of your work are a big plus, so we can all learn together. I have had several Gadget-people critique my Groove jobs I've posted, it's a real help. Even something one isn't proud of- this still gives chance to learn.
so Welcome Aboard, Don!!
