Hello everyone

I wonder if you could help?

Me and my girlfriend are going to be travelling North America for approximately 6-7months starting in July 2013 on a tight budget

We are starting our trip in Chicago and then onto Indianapolis to check out some NASCAR (if it is on)

From there we want to travel to South Dakota to Rapid City and see Mount Rushmore.

From Mount Rushmore we then want to travel to Yellowstone national park.

I am not sure on where to stay, how to stay (camping, etc) and how to get around. I have been thinking about hiring a car to travel around for the time we are there the thing is I am not sure how long you will need to stay at Yellowstone and what there is to see?

After Yellowstone National Park I have found a bus which can take you to Denver, Colorado.

From Denver I was then thinking of flying to San Francisco (due to the distance) and it is relatively cheap.

Obviously be spending a few days in SF and then we want to travel to Yosemite National Park again been thinking about hiring a car to travel California and around Yosemite for the time we are there the thing is I am not sure how long you will need to stay at Yosemite and what there is to see?

From Yosemite we then want to travel California via LA and down to San Diego - not sure what the best/cheapest option would be travelling in California bearing in mind we need to travel to Yosemite. Looking at public transport, looks quite expensive and a lot of travelling around time.

From San Diego we are then going to travel to Las Vegas

While in Vegas we will go and see the Hoover Dam and Grand Canyon

From Vegas will we then fly to Dallas and work our way down to San Antonio (not sure if this is worth doing but would like to) and along to Houston.

From Houston we will then travel to New Orleans

From New Orleans we will then travel to Miami to visit Miami and the Florida Keys.

From Miami we then want to travel to Orlando and do "the parks" and maybe a visit to Daytona Beach

From Florida we then want to travel up to Washington DC

From Washington DC we want to travel to New York

From New York to Boston

From Boston to Niagara Falls and then finish off to Toronto.

We want to see as much as we can and if we can stretch our budget time is not an issue, not sure where to look for cheap accommodation as we are not keeping to dates and most of the hostels requiring advance booking.

Please can I have as much as advice as possible and any helpful information and attractions that should not be missed. We also want to see baseball games, basketball games, american football, etc to make the most of the trip

Thank you in advance
