There was an area that in the town I grew up in that has these huge bushes that lined a fence around this housing development. They cut the bushes back because people where committing illegal acts in the bushes. They where selling drugs, now is this discriminatory? If sex outdoors is illegal there, it is illegal. No questions asked. You can debate if it is right or wrong all you want but until they legalize it they should probably stop humping in the park.
