He sells private treaty. Give him a call in July or August and you can set up a time to look at them. The traders will put a deposit on a calf early but may not pick them up. Cattle change a lot from summer to weaning. I would give him a call now and tell him you are looking for a steer this fall and what you want to spend. Also, tell him how you are going to show the steer (jackpot, county show, major.....)
A couple places we went to, we showed up on weaning day ready to help out and took the ones we wanted home. Be ready at home to handle a freshly weaned calf. (a tight pen, right feed, vaccinate, worm, pour on, shot of antibiotic). Even if you only want one, I would take a buddy for him. They do way better if they have a friend on the trailer and during the weaning process.
Good Luck!
