Hi. I noticed on a travel guide that with Canada so close by one would benefit from having a Passport. My family and I plan to be pretty tied up with just enjoying GNP's splendor, hiking, adventuring, scenic drives, kayaking and so on... Is it totally crazy not to get a passport and take a drive to Canada during our five day stay from Indiana? We are planning to go July 2018. How close is something awesome in Canada to see? We have never been to a National Park before, so it seems like we may be completely satisfied in the Park. However if a Canadian road is so close that we need a Passport to travel , I may look into it.
