I know what you mean about waiting for good conditions. In our early snowboarding days, we'd go out as soon as the mud was frozen. As time went by, we got more and more fussy about conditions. It's a standard progression I think. We get out your way pretty often. We've been snowboarding at Marquette Mt., Porcupine Mts., and Mt. Bohemia. We visit my brother in Escanaba several times a year.
A friend has trailered his snowmachines to the Keweenaw a couple times. Says I for sure need to do that sometime. I look forward to discovering a lot of great trips in the next few years. This summer, we're looking at a bike trip up in the Keweenaw, in July sometime.
The snowmobile trail system in the UP has been a real revelation to me. I was sort of aware of its existence, but until you start driving on it, you don't know how much care and planning, bridge building, signposting, brushing, clearing and grooming it takes to maintain.
Good luck on your new CB project. My 750-Four is good to go for this year, so my current is an 84 CB650sc Nighthawk. What's yours?
