Yes and no.

I rode the 75k early ride, on my roadie (with platforms at the time, got me some kudos from the roadie clan out there, heh ) - my daughter stayed at a babysitter while I did the ride, then I went and picked her up with the aforementioned MTB/trailer combo.

My MTB is a Canadian Tyre Dyno Victory, front fork suspension and heavier than a heavy thing soaked in really heavy liquid - my first owned bike in Canada, and I love it in the winter, it's fully fredded out for all-weather commuting (though I need to do the Clorox mudguard mod Keith suggested).
