re: Traveling advice- New York, Boston, Denver, or Kansas City

Not sure when your going, but if you can go to Boston on July 4th I'd recommend that! Went a few years back and caught a baseball game and after the baseball game saw fireworks over a river (can't remeber name). Stood on the bridge, were tons of people. Was an awesome experience.. I'd also take a history tour! Another thing, Boston is close to NY so if you have 5-6 days you can do both!
