I am working in a Summer camp in Minnesota this summer, and when camp finishes (mid August) I am looking to travel to San Jose to stay with some friends. However I am not sure the best mode of transport?

I am considering Greyhound Bus, AMTRAK (?) Trains or Flying.

Ideally I am looking the most cost-effective way to travel WITHOUT comprising safety (a friend of mine was nearly mugged at a Greyhound station in SC).

I would be making the journey Return, about a month later.

If anyone has any experience of travelling long distance across the states I would appreciate it. Particularly airline recommendations and how much I should expect to pay.

Thanks!
