We think we have found the solution this year! We have bought a "MacGregorEnduro Front Mount Playground Goal."
This rim has a very heavy duty mounting plate that extends around the rim--actually two rims. MacGregor welded two steel hoops together for strength, then fused a sheet metal band below them.
This rim is intended for playgrounds, and, once installed, we expect it to last indefinitely.
We should dedicate the goal to the late Bernie Allen, who served several terms on the board of directors as a member, officer, and president. Every time over the years that someone mentioned replacing a broken rim, Bernie would tell us that it wouldn't hold up. Maybe this time it will.
