Pervert in the Park?

at our neigborhood town park, every morning during the 11:00 hour, a man drives up to this park restroom, goes in, and doesn't emerge for a half an hour. really. he parks in the same spot outside the restroom, does what he does in there, gets back into his car and drives home.

so, what is he doing in a public restroom, every day, for that length of time? is he doing what one normally does in bathrooms? if so, why does it take so long, and why does he drive from his home to do it?

there is something odd about this behavior. a. and i call him park pervert, but we really don't know what he's up to.
