Many state and county fairs include a livestock show. Often the exhibited animals are auctioned off at the end of the show. The animals are raised and exhibited by youth (4H, FFA, etc). The proceeds go to the (child) owner of the animal.
At our county fair, bidding starts at about $3/# on the hoof. They generally weigh between 1100# and 1500#. Butchers present at the auction take your order on exactly how you want it cut. The seller will show up on your doorstep with it cut, wrapped, and frozen. No charge beyond the bid price. Seller takes care of everything. Cost above market price is tax deductible.
Some of the best beef money can buy. Can help fund college. Swine, lamb, goat, etc might also be available at a show near you. If a whole beef is too much, go in with a group. A group of 4 can end up with 100+# each for less than $1000 a piece.
If this doesn't describe a livestock show near you, shop around. If none of this sounds like your cup of tea, forget I said anything.
