My "virgin" trip to Land of Freedom

I'm going to the States in March, for a whopping 3 weeks!!!

A glimpse of my itinery:--
12th to 14th March: Los Angeles... Hollywood Here I Come~!
14th to 19th March: San Francisco... Another Melbourne-like city? (I certainly hope so!)
19th to 30th March: New York... This is where the shopping begins *hiakz* (am going Washington and Niagara in between)

Planning for this trip is more taxing than I thought it would be. The air tix, the hotels, contacting WS for our trip to the Niagara Falls, imaging the hassle to fly from LA to SFO, then from SFO to JFK... Oh well I have only myself to blame... being the usual greedy me, there are so many places that I wanna cover during these 3 weeks -- Hollywood, the Golden Bridge, the magnificent Niagara... all in the name of "since I've fly half the globe to North America, might as well..."

I don't know how this trip will work out to be.. God Bless Me!
