My plan is to simply continue with what I've been doing - between 80 and 120 miles/week. I bought a trainer but I find it too boring so I never use it. It's probably going to be sold. Fenders are cheaper (unless you have four bikes)
We get ice occasionally, but rarely do we get snow that lasts for more than a couple days. It's the rain that lasts for months that gets to me. A snoboard parka with the liner removed is what I use for the wet.
Currently, I'm re-building a '93 Trek 930 mtb to take over the foul weather duties from my deceased 830. It's in the shop right now having the c-rings and cranks swapped over. I like the OvalTech. Just about everything else is also going over to the 930 as well.
