hey...

ok so me and 3 friends are planning a road trip for this october...
the idea is to fly to New York - and end up in Vegas... whilst visiting a few places in between... we aim to do this in around 6 weeks ...

we have a few ideas down already and a list of places to go .. but one thing that is really becoming a worry is transport...
ideally we want to rent a car in NY and drop it off in Vegas... but i cant seem to find anyone that will insure more than 1 person - as we are all under 25...
i was wondering if anybody here knew of a good reliable company , or if anyone has done this kind of thing before could give me some tips?!

apart from that i think the main aim is to visit as many places as we can... are there any places you guys think are a must?!

thanks in advance for any help!
