I told my first year Law School student son that if he didn't take his brother I won't renew season tickets next year - maybe. His brotheris not a big fan - but will probably go if big brother goes. Big brother is a big fan - but has moved on to basketball a bit and is spoiled by the FB TV coverage.
Back in the day when TV coverage was almost non-existant it was tough to get a ticket. That is why I have renewed my mother's season tickets for almost 30 years now. Times have changed.
