While there are a number of great ideas, one that sticks out for me is the ability to remove "impediments" (junk) from a sand bunker if the junk is in your way. Before, if your ball ended up behind a stick or leaf or stone, tough bananas. As you can see from this tip, it's a favorite of mine.
Check out USGA site to see all of the proposed changes. It's pretty exciting.
Enjoy the game again,
