If you are going to the US Open you need to make sure you give yourself extra time. The public "MUST" park at the ORU Mabee Center at 81st and Lewis and take the shuttle to Southern Hills. Busses run every 30-minutes all day long. Many people are trying to park in a lot at Johnson Park near 61st and Riverside. Only US open workers and volunteers are allowed to park there. Officials say they will tow cars parked where they're not supposed to be. There are also several rules people who attend the tournament must follow. Cameras, camcorders, pagers and cell phones are strictly prohibited at the golf course. Spectators are not allowed to bring folding armchairs or ladders. There are no pets allowed at the tournament. The only time cameras are permitted are during practice rounds.
