There aren't a lot of country roads around Ber(zer)keley. The only thing I've heard of for "making out" is Fish Ranch Road.
In Bezerkly, an alley would do. Or the public park at noon on July 4th. Wouldn’t be an uncommon occurrence and it would show how freethinking they are. They’d be unique little snowflakes just like a million hippies since the 60s.
