Umpiring is a skill that takes lots of hard work and dedication. Just buying an Elbeco powder blue shirt and a pair of gray slacks doesn't automatically make you an umpire. Umpires who care about the duty attend rules meetings, go to schools, read the rule book, ask for constructive criticism, and watch veteran umpires.
People Umpire for several different reasons.
Some do it just for the money, and this shows in their skills, demeanor, and mechanics. These types of umpires have their place. Others do it to give back. We give our time and efforts to give back to the community and the game. These are the umpires who always show up with a clean and pressed uniform.
