I have no idea where to start. I am trying to plan a road trip for my son and I who will be 8. I live in Northern Indiana, and I do not want to drive more than 3 days each way, espically since this is our first road trip. I think we are planning to go in the spring, so that we have plenty of time to plan and save money. I need ideas of where to go and what to do, I think that we are more interested in sight seeing than just driving. I would really like some great ideas, espically those that my son would enjoy( worlds largest rubberband, something of that sort) !!!! Also, I am wondering if it would be cheaper to rent a more fuel efficient car for atleast 7 days, or stick with my explorer, which at least has plenty of room. I am not opposed to staying in a " Cheap" hotel, or camping it out for 1 or 2 nights weather permitting !!!!! any help would be greatly appreciated!!!!!!
