Casey Martin will get to use a cart at the U.S. Open.
Jack Nicklaus, Arnold Palmer, and others say that walking (at the PGA Tour level) is an integral part of the sport.
On the flip side, Casey Martin is a really rare exception, so allowing him to use a cart isn't going to open the floodgates or anything. Most people who have a disability like Martin don't qualify for and reach the upper levels of golf.
So add a comment if you'd like, but the poll is anonymous and unless you post to share your vote, nobody will know which way you voted.
