Memorable Travel Experience(s)

While I have had the stepping foot in all fifty (50) states for quite some time with only just a few I only passed through while traveling. Now, I feel I need to accomplish something of significant substance in all fifty (50) states. I have skied in many states out west (and East), like the tough ones, WY, NV, ID, CO, MT. I have now made it a cause to play a round of golf and post a score in all fifty (50) states, and I am at 38 with a Utah visit scheduled in October for #39. I am in the 40's with a picture standing at the "Welcome" border sign. I have also visited 25 of the 30 MLB ballparks.
