Shoot, here is a "portable" loading chute that our neighbor was using in 1977.
And here is the squeeze chute that we were using the same day. My cousin, Ken, is the cowboy in the photo. We were helping our neighbor, John Burton, work
yearlings that day. Shoot, the chute didn't even have a floor in it, so once in awhile one of the bigger yearlings would try to take off with the chute. All joking aside,
that was a fairly up-to-date squeeze chute for that era. It had more steel in it than some of the pure wooden versions that were in use.
