I absolutely agree that the more the endurance factor is, the more you will remember it. When I saw the title of your thread I immediately started reminiscing about some of the 500 mile days in the snow/rain, 34 degrees or the breakdowns in God forsaken places and the challenges those rides presented. Most don't need to be embellished. They are truly as 'bad' as remembered. I look back on those times with a smile. I think it's in the human psyche to take pride in conquering adverse situations. Also, I've, almost without fail, met helpful strangers and saw out of the way places I might have otherwise missed. Some of the friendships are still strong. Those 'worst trips' are what makes for adventure. I love road trips, no matter what the vehicle, because of the unknown.
