A little help.

[travelbug]

Hey Everyone :),
Me and three friends are planning a road trip across USA, in 2011 (I know its early) once we all finish uni. We are looking to plan well ahead to ensure we fit in as much as possible. We were hoping for 3 months away. I want to give you our 'idea' leg by leg to make sure we are being realistic. We are planning on travelling New York - Los Angeles.

Our first leg:
New York - Cleveland.
Staying 4 nights in New York
Staying 2 nights in Buffalo taking in Niagara Falls
Staying 1 night in Cleveland taking in the Rock n Rock Hall of fame.
Is there anything else between 'must see of famous spots' we could stop at.

We want this trip full of memories :)

Thanks
