Because I'm old, I get in for $1 in the Albany Clubhouse Racebook. Regular price is $2. I can get in free on Sundays during football season when I wear a team's jersey.
Back in the 1980s I was living in Suffolk County L.I. and there was an OTB Teletheater, I think it was in Hauppauge, where not only did you have to pay to get in, but you had to be wearing a sportscoat. If you came without one, they would give you one to wear while you were there. When I moved to Albany, they had a dress code at the Albany Teletheatre that include no jeans. They removed the dress code years ago.
