I lived in Brawley briefly and in all honesty, it was a forgettable city that I definitely won't miss living in. It's far inland and due east from San Diego so there isn't much to do there unless you feel like driving a while. There are little opportunities for work and even fewer for education, so it's not a place I would recommend to anyone. The summers are hot and the real estate is very cheap, probably because the crime here is a bit high.
There is a Walmart Supercenter here, which is one of the few places you can really get some shopping done. Apart from working and checking out the few public parks in town, there really isn't too much to do here. It might be a good choice for people looking to retire but even then, there are better cities to choose from that are just as warm and affordable but have more things to do.
