Not sure of any clinics but there is a show coming up on Sunday in Loveland just off of I-25. You could walk around and watch, most people if not too busy would at least answere questions.
I think kvhranch is looking for a cattle fitting and showmanship clinic aj. There was one in Sterling last year during the first part of June. Check the Stierwalt website for the schedule to see if anything is lined up in your area.
Sullivans is putting on a free clinic after the Beef Brawl in Sterling on April 16th. Give me a day or two and I will have the website updated again. www.beefbrawl.com. We would love to have you at the show, then you can stick around for the clinic.
