Dont know what the answer is to this, why do we  seem to build skateparks in certain parks of the our cities which are in the middle  ?.

I think on one hand if it gets a bunch of kids interested on doing something it is very good, and pays in the long run.  Even if it gets a few locals focused on doing more with there spare time will benefit the local area in someway.  They may encourage other kids to get involved and using a skatepark or BMX track and hopefully slowly build more activite groups and future generations. However then you get the mindless few who can spoil it for them and others and put them off going especially when they are short in numbers.  You often hear stories of items being stolen, users being threaten or beaten up, stones being thrown and the ususal bottles being smashed when they get drinking.

Do you have the parks fenced off and opened and controlled by the council, say like Bridlington. But have a very minimum day charge (say £1.00). So its still open to all.

Or do you have more parks, in all types of area's ?, and just get on with it.

Where do they situate skateparks in the USA, away from housing estate, in large city parks. Is there any lessons we can learn from them.

As some Council could possibly say, we spend all this money and nobody really uses it (generalization), although this could be down to it either being built in the wrong location or built with little consultation like they did in the 90's.
