Go for it and have a plan B. I have been a dirt bag climber and skier for decades, and happen to drive a Accent as well, the hatchback. Strap the skies to the roof but be sure they are in a ski bag to protect from road salt and go for it. I have no record, short hair and in my 60s. I still sleep in the car and ALWAYS wonder what new adventures will come my way crossing the border. There is no reason I can figure out why I have this issue but I always assume that I will get searched, take no chances with anything "illegal" in the car. Have enough cash/credit cards to make it look like you can afford your visit, and have a specific destination in mind, even a specific accommodation you may stay at even though you have no intention of staying there. Based on my past history I always carry my passport when I travel, think you need that for Canada anyway. Keep your beard, keep your mouth shut, and follow their directions - no humor for sure. To be honest I have more issues returning to the states than leaving.
