Michael, in the spring, bump-and-run is not required as green is soft enough to hold most long iron shots due to rain. However, in mid-summer when it is rock hard and running around 10, it will be impossible to hold with long irons. I am really hoping that it will be that case for the US Am.
And Carl, the Friday afternoon is really going to depend on the weather. If the weather is good, if you do not have an advanced reservations, it will be tough for you to get on. I would reserve your spot right now and cancel before the penalty (48 hours) if the your plans may not work.
