English rider just moved to CO -- looking for Western instruction

I just moved to the Boulder, CO area from Massachusetts. I have been riding for 17 years – mostly saddle seat, but did the hunter/jumper thing on the equestrian team in college, and hunter on the flat since. I am looking to take advantage of being in the west for a couple years and would love to learn to ride western, maybe try out some barrel racing, etc. while I am out here. I don’t really know anyone here, let alone horse people – any recommendations for barns and/or lessons in the area would be greatly appreciated!

Here is a Quarter Horse show barn run by a very capable and honest couple.

They could teach you to ride western correctly and maybe try some trail courses. That would get you some good basics.

There is the Mile High Barrel Horse Assoc. also that might direct you to a barrel trainer in your area with lessons
