Reunion trip for Petr and Vanessa

The essence of the trip would be meeting my old love - Vanessa. Me - Petr - international student from Czech Republic - participant of Work and Travel in USA - working in YNP - Old Faithful. Missing her company very much (not together for 4 months now). If I lured her to USA, it would be great! The best would be meeting in Bozeman, MT. She would have to take a flight from Berlin, as she is living in Germany.
My contract in YNP is finishing 17th September, then 6th October is my scheduled flight back - from N.Y. to Prague.
After her arrival, we would travel around the U.S.A., as traveling alone brings no fun. I need her company.
We would rent a car and go down the south. To see all the beauty down there - Rocky Mountains, Death Valley, then visit our friend Joshua in Denver, continuing to L.A. and San Francisco. Vanessa is half Canadian and has relatives in Florida, we would like to visit them too. Then getting back west, driving along the west coast to Seattle, to visit our friend Martha.
Hopefully this trip would bring us back together again, help us to find happiness again. As now we are apart, and it brongs no fun as well.
