Replying to Random Road Trip

So I have a few days off this week and am thinking of going for a road trip. Basically, I'd like to drive two days (there and back) and have one day to wander and hang out. I live in Calgary and I'm thinking I'll either:

- drive out to Vancouver or Seattle, hang out for a day and then head back
OR
- drive down to Jackson and check out Grand Teton and/or Yellowstone for a day

I'm leaning a bit more towards Jackson just because I haven't been down that way before, whereas I've seen a bit of both Seattle/Van. Jackson is also a touch closer (negligible though). I'd also probably wander a bit more if I do that.

Thoughts?
