It would be a good idea to go visit the police and get acquainted. The only nighttime outdoor hobbies they are familiar with are burglary, vandalism and so forth.
+10 on this. Back in the late 80's I worked nights stocking shelves at a grocery store. We didn't have cable or anything like that, and the TV and radio stations we did have went off the air at midnight. I used to spend my nights off just walking around town and got stopped by cops a bunch of times even after they knew me...or maybe because they knew me.
