I cannnot decide...

I have to quit my job on 23rd Oct because I have to close my bank account before I back to Japan. If I work till 23rd October, I can get my last salary on end of this month. The next pay day is middle of November so I can't wait till then. I have 3weeks after that, that's why I'm planning to go traveling. Although I cannot decide where to go. One of my plans is just going to Las vegas and Grand Canyon by air, the other one is to go to western part of US include Sanfrancisco, Los angeles and Las vegas by long distance bus which is called Greyhound. I can ge t Greyhound Discovery Pass which means free ride pass in Canada, US and a part of Mexico. It costs about $480 in 15days free ride. It's so fantastic but there is the reason why I cannot decide it. I know there is the most important thing to travel by myself, that is INFORMATION!! But I don't have any guide book of US, so I cannot get any detail informations about western part of US.. It's too big problem for me.. Of course I can get some infos from internet site but I cannot check web site too much while I'm traveling. The first thing I have to do is to get some guide books, so I contributed to internet board to find someone who can sell me the book. I hope that comes true and I can make wonderful travel plan, there's not enough time for me to decide it.. Hurry up..Please hurry up..
