I'm planning to visit the US next year, most likely in May/June for a month, where should I go? (I've already been to Washington DC and Chicago?)

California particularly San Diego. 300 days of awesome weather. Sun kissed beaches. Mountain ranges. World's best zoo.  Zoo safari. Both are different. Sea world shamu. Gliders. Hot air balloons. Then proceed to Los Angeles. Should I list everything here to see. Don't miss Las Vegas. Not far away from California. So much to loose there. Happy journey Without knowing what kind of music you are interested it's difficult to answer. I am myself huge carnatic music fan.

It really depends on what you're looking for. I guess the most common options would by NYC, California (LA and San Francisco), Las Vegas etc. I enjoy country music, so personally I would want to visit Nashville,Tennessee, although I'm not sure that would be too appealing an option for someone who doesn't. I feel you should do some research on your own. I mean, I'm pretty sure most people would find the options I listed earlier to be rather "cliched"(and so do I, to an extent). Asking others to decide where you should go might not be the best way to go about this. But that's just me.
