You're getting way too overheated about this. Take your passions out on the guy, not the rest of us. Think about this, for a minute: Runners search around, far and wee, for a quiet, untrafficked area they can run in, in peace. And for a while, it is just runners. And even people who skate as well, and walk long distances as well, and ride their bike as well, and jog with their kids ONLY go to this specific place to do their race training. Some people are running an under six minute per mile pace, and all is well. And there's enough runners, that women running by themselves can race train in peace, and no right minded bad guy would mess with any of these athletes. But legally, others are not prohibited. And so in time, other people start congregating in this runners venue, because they wanna be hip or they wanna boy watch or girl watch or they're looking for safety in numbers - or they resent the runners and just want to mess with the runners. They bring their Walkmans, they bring fat tire bikes, they bring their Mom with her walker, and they bring skateboards so they can skate alongside a woman and leer at her and harass her as she runs. I watched a least 6 such venues come and go as places for runners to run in peace, because the general populace were drawn like flies. Mixed with the miscreants that couldn't get a foothold when it was 100% footracers. They could not, would not leave us in peace. And then when we runners left, and critical mass was lost, then these hangers-on abandoned the places again and in some cases, the cycle repeated itself three years later. A handful of fast people, then twice and three times as many, then the flies arrive, and the percentage of fast runners crumbles, and eventually falls to zero, and the place reverts to a desert. Different parks, different parts of the same park, areas adjacent to golf courses, levees, track and field facilities, utility rights of way, college campus expansion areas, spillways. Mountain bike "courses" got invaded this way as well, sometimes. Put yourself (I'm pretty sure you can't) in the mind of the serious runner, who helps create a safe environment and then gets treated like schidt for having done so. I'm not really expecting you to understand what's going on in the mind of a runner, but someone else will read this post and they may be swayed a little. Runners who have been repeatedly evicted from their running haunts, all respond differently. If we're looking for motivation, maybe this could be a place to start. Although, this guy could be a sick assailant disguised as a runner. There have been numerous cases of this as well. We used to have the same thing happen, in canoeing. Some of us would pioneer new canoe runs, after befriending landowners and working out places to park vehicles and walk around obstructions. But someone in our party would share with the wrong person, and suddenly the nudists and druggies and drunks would show up en masse, and damage the landowner's gate and allow livestock to escape and change clothes in front of the landowners grandchildren and the next time I went there, the landowner could barely bring himself to speak to me. I had the makings of a canoe trails manuscript basically done, and I decided publication was a really bad idea. Someone else cribbed off it, made some cute changes, and they published it anyway - now, the activity is basically dead. Pedestrians in our society walk (whether they wanna admit it or not) under the protective shield of runners in many places, and it would be unsafe without these runners and other active people, but when it comes to determining the amount of right or privilege an active person should be afforded, he or she is seen as scum.
