U.M. ARMY Is the best thing about Mission Milby, in my opinion. The Labs in this facility are AWESOME!!!!! I really love the environment in the place, it bring a sense of happiness to me. U.M. ARMY is my favorite experience of it all. U.M. ARMY stands for: United Methodist Action Reach-Out Mission by Youth. It is a amazing camp where High School Kids can go help there community by building a ramp for an elderly person, or patch up a roof for a needy family. I have been visiting Mission Milby for about four years now, when I started I absolutely fell in love with it. I'm going on my fifth year and I don't regret it. I would really recommend to any random person willing to come. It is just amazing.
