My home course is 9 hole Muni Executive. The reason I play here is because it's extremely affordable ($345 for an unlimited season pass) and it's on the way home from work and only 10 minutes from home and because my game sucks. It's a short course and the course conditions are only about average but I'm not much of a range rat and prefer to practice on the course so I tend to play 3 or 4 times a week after work trying to hone my irons and short game. (to no avail sometimes but I'm an golf addict) Also the pace of play hasn't been that bad the last two years. (probably due to economy) Last year alone I played over 50 times and in the last 2 months I've played over 20 rounds already.
That said, on weekends I will always seek out a different course to play. I will try to find an 18 hole course to play within a 30 mile radius, either with friends from work or by myself. Cost isn't an huge object but if I find an affordable course I will play it a few times during the year. I try to seek out new courses to challenge myself and see how my game has progressed. Variety is the spice of life.
