Err, I don't know whether to say thanks for all your replies or to be worried that this doesn't seem to be such a rare occurance. But I guess the countles numbers of runners who havn't had anything nasty happen to them won't be posting, so we should put it in perspective.
The wood and bottle-throwing incidents happend around christmas, when I was still living in northampton and running round a slightly dodgy (but by no means the worst) area of the town.
Now I've finished at university I'm back living in Boston, Lincolnshire (until I can get a job anywhere else). The odd thing is, up till thursday the worst I'd encountered here was a couple of 10 year olds hilariously trying to block the pavement in front of me, only to look sheepish when i simply ran onto the empty road for a couple of meteres to pass them.
The airgun (or whatever it was) incident was actually on what must be the busiest road in town, at about 6.30pm, so its not like it was South Central LA. from what I remember of the car that went past, it looked like it was a family coming back form holiday. Skegness is only 20-odd miles away, and this would be the road to go anyway south from there. My guess is that it was a family going back to wherever because the weathers turned crappy these last few days, and the kid had probably won this thing on hook-a-duck or whatever.
I really don't think that the town has too bad a problem with this kind of thing, at least in the daylight hours. Boston has plenty of herion addicts and skinhead neo-fascist nutters like any other provincial town, but if you kep away from where they hang out you're generally OK.
I think the number of mindless attacks of all sorts on runners is indicative of the rising levels of crime and violence in society as a whole. I think we all know of places we really shouldn't be running. Boston has a population of 30-40 thousand and theres a couple of areas that I wouldn't want much to run round. And no, Snicks, I don't think you should really be running alone at night. We all (or most of us) run round, just like Shattered Shins say, relying on luck and the thought that stories like Dangly Spice's "won't happen to us". But we'll be out there again on sunday, and next week, and the week after that (unless my knees totally go AWOL on me), because we're runners (or want to be) and we won't let the b*stards grind us down. rain or shine, bricks or burning cars (how I miss northampton!) we'll still be pounding the roads.
ooh, thats almost made me want to go for a run right now. But its 2 in the morning, so probably not a good idea. ;)
