The annual Fort Lowell Shootout is this Friday through Sunday January 15-17 at Fort Lowell Park (Craycroft between Glenn and Fort Lowell).
It's a large youth soccer tournament and brings a lot of young soccer players and their families to Tucson for the weekend.
There is heavy traffic during the day in that area around the park. Don't run over the kids because it'll make them mad and they wear cleats. If they kick you it'll leave a mark.
