Dood come on out to Chicago and do that century. You'll soon find what I mean by compromising safety. Tomorrow, the high is supposed to be 1 C, and that's before factoring in wind chill. By the way, the wind is supposed to get as high as 37 km/hr. This is what I would call a semi-good day for us. God help the Canadians, who get worse weather than us!
I know the century per month is one century per month, hence my caveat about being safe. If it were 100 miles in a month, I would feel a lot better about promoting it, as it would be more realistic for people in colder climes, but as it's an actual imperical (100 mi) ride, that changes the playing field a bit, I think.
Seriously, Chris. You are welcome to come on down here to Chicago and ride a month out here. If you plan for February, I'll put down my sleeper sofa, and you can see for yourself what I mean by unsafe conditions. It would do you some good to see how the other half lives every now and then....
Unless you can make consessions for those riding in the harsh winter climates, I think it's more than fair to say that if you've got bad weather, and you're feeling like your safety is compromised, you can be able to do your miles on the trainer. Besides, the way most people talk, it's like those 100 miles would be much harder on a trainer than riding outside anyway!
The welcome wagon is here for ya anytime, gorilla boy!

You sound a bit soft anyways....
