Alot of people are flying in...obviously they are not tracking their cars, but they are their to hang out.
I dunno the driving time from Montreal. I'd imagine...20+ hrs? Might be long, although I drove to NPM04 in Pa, from TX = 1400 miles, 22hrs. And we did the leg home in 1 stint with only a 5 hr nap. Got to work at noon Monday...

If you time it well, and/or drive like a mad man you can always make it fit around work
If you are from Cleveland you should check out ohpoc.org. I know that is their website, including one of the founders of NPM.
