Why do NFL teams practice at different locations?

NFL teams practice at different locations to optimize their practice environment and to optimize their preparation for a given game. Teams practice at their home stadium, at their opponents stadium, and also at neutral locations. Practicing at different locations allows teams to get familiar with different surfaces, different climates, and different playing conditions. It also allows teams to gain a competitive edge by studying their opponents practice habits and getting used to the environment they will be playing in.
