I'm nearly 64. We don't live in Utah but I've had season tickets for some 25 years, taking my kids to a couple of games each year. We also took them to some away games such as NM, UCLA, ASU and the Holiday Bowl. We've done the same in basketball.
My oldest son will turn 40 soon and we still go to games together, now taking grandsons/daughters. My daughters still love the games as do their children. The WCC tournament is now an annual event for me and my 3 sons. We have such a great time, my daughters now also want to go. This year, we'll probably rent a house and take all the children and grandchildren.
Your son will always remember the games.
