There are several places in Colorado for retreats. Most places aren't already set up with cutting tables and ironing boards though. I know the Greeley guild goes to some place in Highlands Ranch. There's a place somewhere in the Canon City - Co. Springs area called The Abbey I've heard good things about. There's a really nice B&B in Black Forest that might make a good retreat location but you'd probably have to do something else for food because I think she only does breakfast.
