If you're on your way to visit America, here's a website that will help you find your way around! It's what i use when it comes to buying tickets to particular entertainment that i wish to see while im there, but also they have great city guides! www.ticketamerica.com
Next time I get to go there, id definetely buy some la lakers tickets before i go, so i dont have to worry about getting a good ticket while im there: www.ticketamerica.com/los_angeles_lakers_tickets.html
or why not get some other games in while you're there, here's some interesting teams to watch!
There's no way better to experience America without throwing in a typical American sporting event and experience. If you get it organised before you go there, your experience will be all the more fun!!
