We lived in La Mesa about 10 years and moved to North County about 3 years back. La Mesa is good place to live. Less traffic, malls are not crowded and very very less anti social and criminal activities. We moved from La Mesa because of the following reasons. Most of the homes are very old (40 years plus) and small. Schools are not good as per API scores. Old people are too many. You do not see lot of kids. Any how these observations were valid 3 or 4 years back. Now I heared lot of young families are moving there.
