To clarify: Not all riders are Sasswipes. And, yes, I find that the older riders are infinitely better behaved and easier to get along with than the young Lance-types. But, I have found my share of 40-somethings (I'm 46) that are always insisting that their equipment is the best and how much it all cost and blah, blah, blah...all that ego stuff that I find rather unappealing.
Thus, I ride alone more often than not.
