I bought a glider this year, so I don't have to go outside in the winter weather!
BTW, I looked outside -- no ride today...MUD.
I prefer the outdoors... but if I was where the weather wasn't tolerable most of the time I guess I'd have to have indoor equipment. I don't care for Fitness Centers either. I try to ride about 10 miles each day and if it's too bad to ride then I try to walk about 3. Some days are a total washout.
