Thanks for all the tips mentioned regarding New York. I know it wasn't my thread, but thanks for the tips anyway.
Has anyone been to Los Angeles? I will be in LA at the end of August. I don't want to do the usual movie studios and only have the following:
Midway Aircraft Museum
Natural History Museum
Page Museum L Brea Tar Pits
I will be all 'museumed' (is that actually a word?) out by the time I get to LA, as I will have visited a number of museums by then, including the Smithsonian museums in Washington and Virginia. Now that is something I am really looking forward to seeing!

I am allowing two full days for them alone!
Also, any tips for Chicago, as I will be there for a day or two. The only place I have for Chicago is Astro Physics.
So, any suggestions for LA or Chicago would be appreciated, thanks.
Leaving at the end of July and returning at the end of August.
Should just about have everything booked by next week. Is July here yet?
Cheers Peter
