boulders not a lot better, without traffic, i can get from foco to summit county in about 2 hours, from boulder its maybe 20-30mins faster. regardless your getting in your car and driving awhile. plus the big problem is I70, i've sat in that traffic for 4+ hours trying to go skiing for the day, usually more getting back, anyone going from the front range to summit has to deal with it.
the good thing about foco is you're 3 hours away from steamboat, which is an awesome mountain, and you'll never hit traffic going up there. a guaranteed 3 hour drive is way better than hoping you dont get stuck in traffic for 5+ hours(which is pretty likely) plus theres good backcountry close to us up around cameron pass, and you dont have to live in boulder..
