A Neighborly Vent

We have a neighbor who seems quite nice. We exchange greetings occasionally, but he generally keeps to himself. Lately he's developed the interesting habit of snow blowing at night. Apparently prime snow blowing time is between midnight and 3 AM. It drives me crazy! Now, I don't know if he has a job with strange hours or if he enjoys being out at night, but I don't know what to do. We don't talk a lot and I don't want to be the rude neighbor complaining about his snow blowing. It's not keeping me from falling asleep, but it does make it harder to do so. I guess I shouldn't make it into an issue. Snow blowing is only necessary after snow falls, so it's not like this is a year-round hobby. I just hope he doesn't mow the lawn during the same hours...
