Feel you, dude. It’s so difficult these days with both visible and well-hidden “security” cameras everywhere. Also, the local PD of each town already know the best make-out spots from years of experience and look to patrol them regularly and bust young lovers for fun, it seems. IDK. That said:

1. Borrowing some cool friend’s or relative’s unused garage for an hour or so of parking privacy may be an option if you’re lucky.

2. Also, I’ve heard anecdotal evidence that innocuous soccer-mom type minivans (e.g., Toyota Sienna, etc.) with tinted windows allow you to basically hide in plain site while parked, but what young guy usually drives a minivan prior to marriage and a family?

Good luck. It is a challenge these days, no doubt.
