Charleston sc. To fort colins co.

Me and my girlfriend are moving to Colorado in 3 months looking foward to the out door world and nature of Colorado, but we dont want to give uo our love of putting on nice clothes and going day strolling through town the way charleston offers itself up in that regard.there are many great restaurants and i mean great! Here we enjoy that, along with night dancing. Is this the best city for us in colorado or would we be better off in Denver. I dont want to loose to much of the cosmopolitan life style
