You have the Day Trawler. These people are quite content to sink their line for the day. They will block a lane and hope that someone walking by is the owner of one of the vehicles around them. Time is not an important consideration. They are quite happy to wait as long as it takes until someone comes out to open up a spot for them, regardless of the procession of vehicles now stacked up behind them.
Finally, there’s the Circuit Trawler. They are the total opposite from the Day Trawler. They are content to drive around and around the parking lot at slow-slow speeds looking for a parking stall. The confusing thing is that they have range issues. Circuit Trawlers will drive by empty stalls and keep circling because the available stalls aren’t close enough. The other week, I pulled into mall parking lot. It was busy, forcing to me to park a hundred yards from the entrance. The Day Trawler behind me continued to circle and circle while I walked all the way back to the mall and entered.
This last point highlights the futility of trawling. Sure, I’d love if a parking stall would open up in front of me every time I went anywhere. I would also love it if Salma Hayek and Angelina Jolie would carry me everywhere in a chair, but I’m not going to expect it. I guess trawlers think they’re special–and they are. It’s just that they are special needs.
