There's alot more to an experience than just miles and time. It's how you deal with all the changing conditions, and knowing quickly how their going to affect you. Like tracks, at all different angles, rocks, gravel, animals, a nice smooth sweeper and then oh-crap there's a slick mossy runoff right as your coming out! If you don't have miles on your bike you wont see half of these once, and if you don't have time you wont know how to deal with it again, or better. The worst thing in my opinion is being too cocky when you on your ride, lets face it not only do you have to ride your bike but you have to pay attention to everyone else too! Driving within your feild of vison is probably the safest way to ride but how many of us do that ALL the time? If you think you do the next time your haulin down your favorite twisty road just think,,, If someone or something was blocking both lanes could I stop in time?
Don't get me wrong I still have fun on my bike, but I'm experienced enough to know what I'm risking while I'm doin it! I ride totaly different when I've got someone on the back, which means I probably could ride safer by myself? I've ridden long enough that I've been down a few times and if your thinkin well that meens that your a better rider than me, maybe you havn't enough time/miles under your belt to realize there are some obstacles that we just don't have the skill or time to negotiate!
