Another vote for So Cal. If you want mountains, there are plenty of them here and temperatures are in the high 60s or 70s on most winter days. Orange County has 150 miles of bike paths which do not allow cars. Also, most of the streets have bike lanes down each side of the road.

Those above who claim CO has "terrible" riding most likely suck at climbing... Take such comments with the appropriate amount of salt.

I've lived in San Diego, the SF Bay Area and Boulder. CO and CA are both great. You have to be a little flexible about what you're going to do in CO in winter, but you can ride in every month, just not on every day. You do have to make a bigger investment in winter riding clothes, and maybe go cross country skiing instead of riding sometimes.

I would move back to CA, but there are just too darn many people, and I can't afford it. CO is a little less crowded and a little more affordable.

Munich, or thereabouts. Access to everything.

This.

I beg to differ. Here in Colorado Springs we get 330 days of sun a year. That's more than San Diego, my friends. Sure, it gets colder here, so if you can't take the temps, your argument is quasi-valid. I did 300 days last year, and that was only because for two months I was only getting three hours of sleep, wiping me out. I was raised in NorCal (Santa Cruz-ish), and Colorado is far superior.

I'll try and provide some useful information for once.

If you're flexible in the winter and choose a town over a city, it's hard to beat Boulder. At least 300 days of sunshine and a platinum level cycling infrastructure. On days when there's snow on the ground, you can be in Chautauqua in minutes or Winter Park/MJ, Loveland, Breck, Keystone, A-Basin, and Copper in two hours. Eldora is 40 minutes away.

You can live out of town surrounded by protected open space or downtown near Pearl St. After a short ride out your front door, you can climb all day.

Should I look up the term sarcastic for you, or would you like to google it yourself?
