I'm the only Canadian that thinks Tim Horton's coffee is brown water. I get it from a business standpoint - you add too much flavour and some wiener complains. The dark roast is, I'm pretty sure, the same coffee as the regular brew. Never admit you don't like Timmies to a construction worker. Apparently your life is worth less than the honour of their preferred sub $2 coffee!
So what is it you're getting? 17 hours is a long way for an arcade but I like road trips so I would likely do it myself. Although that stretch of highway is not high on my list of fun road trips (I really like the drive across Vancouver Island to Tofino for example.)
