Since the policy is
a) when a member of the HOF dies, the flag will be flown at half mast...
then the grounds staff must obey the policy to be in compliance and keep their job.
I lived near the Football HOF for 6 years in college and just after.
While I was teaching in Akron, I literally drove the school van past it at least 12 times a year for various academic competitions for Academic Challenge, Science Bowl, etc. For personla travels, I have literally driven past the exit at least 250 times.
I never once went to the HOF. I am a huge fan of pro football. I never went.
My son went with his Boy Scout troop on their way up to the Adirondacks to go camping and canoeing. He said it was awesome. He was upset when he compared Kenny Anderson's stats to a bunch of the QB who were in since he grew up as a Bengals fan and loved the left handed (like him) QB that took the Bengals to their first SB loss to Joe Montana's 49ers.
But I have never been. You would think that with the amount of pro football fans within a 4 hour drive (Lions, Steelers, Colts, Brown, Bengals, Bills) that they would do more advertising. If you go to 6-7 hour drive and you get even more fan bases.
The HOF in Canton just doesn't change and because of that it finds it hard to attract more fans.
