The original list of 100 still has 28 items left. I've crossed none off since my first post discussing them. I've already mentioned 25; here are the other three:
Walk Through a Battlefield - Not, of course, while the battle rages. After. Long after. My first choice would be Gettysburg, although Normandy would be worth seeing, too. I have one friend who suggests that visiting the U.S.S. Arizona memorial should have satisfied this one, but it's not really what I had in mind.
Set Foot in my 50th State - I still need to set foot in Alabama, Alaska, Georgia, Idaho, Illinois, Indiana, Iowa, Kentucky, Michigan, Minnesota, Montana, Nebraska, New Mexico, North Dakota, Ohio, Oklahoma, South Carolina, South Dakota, Wisconsin and Wyoming. This fall, if I visit Notre Dame for the USC game, I might cross four of these off the list. Next summer, a drive to Yellowstone and parts along the way could pull another 3 or 4 off the list.
Hit a Home Run - That I haven't done this one is somewhat embarrassing. But I only played three seasons of little league and in those years, there was no fence, and I was a light hitter. Over the course of about 45 games, I only smacked one that would have gone over the fences that they built later. On that hit, the leftfielder chased it down and threw me out at third. Maybe someday I'll get sent to a mental institution where I can play softball at recess and check this off the list.
