I have looked into that a little bit. I found one company so far (I will look for others) but the costs are pretty high.
To be honest, they were renting out brand new 1500cc Harleys! but even for 650's I am looking at about $800 a week, which, to be honest is just too expensive, since my travel budget needs to last for 14 months!
I will look aroudn more as I am sure I can find cheaper, older bikes for the period. But buying/selling should theoretically give me a free bike for the 3 weeks.. but obviously with added hassle.
Damn, there are so many options! I think my decision will come down to pay for convenience, or struggle for the shoe-string!
This is great advice, thanks guys... keep it coming.
I am so excited abotu this trip.. and the US stint will be good practice for my 6 weeks biking round New Zealand in January 2008!
