My girlfriend and I are two college students looking for a unique, challenging, and rewarding experience for the end of this summer. We have decided to hit the road and go coast to coast and see some friends on the way. We have been reading this forum and doing research for a couple months now and want to see if the members of this forum have any advice/guidance for the trip (cool places to see, possibly unforseen obstacles, cost, etc.) The trip will span 2 weeks, here's the plan;

Day 1: Leave from Fitchburg, MA early in the morning and take I-90 to Flying J in South Beloit, IL.
Day 2: Next morning take I-80 to friend's house in Boulder, CO.
Day 3: Spent in Boulder
Day 4: Drive to and spend the night with friends in Castle Rock, CO.
Day 5: Leave in morning and take I-40 to Flying J in Winslow, AZ
Day 6: Go see the Grand Canyon in the morning and then hop back on I-40. Stay with friend at UCLA.
Day 7: Take I-405 and I-5 to San Diego area. Beach. Stay in hotel in La Jolla. (already booked)
Day 8: More Beach and then take I-8 to and stay at Flying J in Eloy, AZ.
Day 9: Leave early and take I-10 and then I-20 to Flying J in Dallas.
Day 10: Hop back on I-20 all the way to Flying J in Carnesville, GA
Day 11: Take I-85 and then I-95 to stay with friends in MD.
Day 12: Drive back home to MA

P.S. I do realize that this is quite ambitious. I do not expect it to all go according to plan, so I left a couple days of wiggle room at the end. Unfortunately, the plan includes a lot of nights sleeping in my Corolla. But, being college students, we don't have much money to work with, and not taking the trip is not an option. We are saving money faster than we thought, and it is my understanding that some Flying J's have lodging, so maybe if we save enough we could get a room a couple of those nights instead of sleeping in the car. We have a approximately $2000 saved to this point.

This road trip is planned to be trying on our resolve, our relationship, and our sanity; but also a lot of fun. Thanks in advance for your help, guys!

Love,
Luke
