Quote from @Laura Yelin: Hello BP'sI like Sherman...I lived there for about 3 years many years ago and still sell and rent there.It's a slow wealth building market in my opinion, not get rich quick.Mostly blue collar stable town.

This is something I try to live by and teach my kids if I can - "A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly.
