I did take the car to a nearby Jiffy Lube to get an oil change. The location I went to had a Jack in the Box next to it, so I was able to eat while they took care of the car. Of course, when I came back, I think they had 5 different "additional services" they tried to sell me; while I'm obviously willing to overpay to get an oil change, I'm not willing to overpay for the other services they offer.
What's keeping me down, though, is the continuing ant troubles at home. At this point, I almost feel like it's a pointless effort to keep them at bay; we track down one entry path, and they come from another in a day or two. I need to schedule the apartment complex's exterminator, to see if they will have any more luck that our self-service spraying.
