Discrimination

(Click on photo to enlarge)
At Raymond Rimkus Park in Leon Valley, I spotted this
list of park rules.
The one that states "Alcohol Limit 12% By Volume" strikes
me as blatant discrimination.
Beer and wine drinkers can get lit in the park, but those
who enjoy whiskey or vodka cannot?
Makes no sense, especially since you can pre-mix a jug of
screwdrivers or rum and cokes, which will get you below
the 12% limit.
You just can't do shots?

Sounds like a challenge to me.
I'll be breaking this rule on Saturday--wish me luck.
