Overplanning to Avoid a Strict Driving Schedule/ Interesting Canadian Destinations

I've decided to stay away from a strict schedule with pre-planned nightly stops. I think I'd be opening myself up to too much stress. I'd hate to push myself too hard and drive when I'm too tired just to get to my night destination and I'd hate to have to stop when I still feel like driving just because I've already reached my planned destination. I'm also thinking the amount I'll want to drive in a given day will be heavily influenced by the terrain.

I've started making myself a chart which I've populated with destinations along my route. Each destination is at most a few hours apart so I have the freedom to add or subtract a few hours from my daily drive while still having an idea of where it'll put me in terms of the next days driving. You can see it here, but just remember that I'm still working on it. I honestly don't know why you'd want to look at it, though. It's painfully boring. I'm just a nerd and happen to like lists and charts. A lot of planning is needed to avoid strict schedules, you know.

In my online searches I've actually found a few interesting places in Canada that I'm thinking of stopping.
-Signpost Forest - In 1942 when the Army Corps of Engineers was building what is now the Alaska Highway, a homesick engineer put a sign in the ground with the name of his hometown and the mileage from his location. The tradition caught on and now there are over 50,000 homemade signs and license plates hanging there.  I'll try to hang one for Swampscott while I'm there - too bad I don't have more time to make a quality sign.
-Liard River Hotsprings - Exactly what it sounds like! Natural hot springs in northern British Columbia. They have a lodge there, so I'm going to try to finagle staying there.

If you're ever planning a road trip, I highly recommend this site. It isn't very flashy, but it has really good information.
