Is that the bit of the Parkland Walk where the derelict playground is?

I'm confused as to how this is a new park for the area, aren't you just telling us that a school is being built on the old park? Do you mean the new park will be on the site of the old school?

The maps at http://www.parkland-walk.org.uk/ show it as more-or-less where the adventure playground is, though the main building is higher up the embankment and further west away from the main road.

Good. Else where would the future trains go?

There's a skateboard facility in Finsbury Park, can't you use that one instead?

I often wonder why there aren't more of these facilities and why the ones there are are really small so that only one person at a time can use them. I mean the one in the park is titchy, yet there is a massive concrete area next to it that doesn't get used for anything at all. They should have made the skatepark cover the whole area so that more people can use it, and maybe have different bits where little kids and those less skilled can skate and the bigger kids and adults can have their own bit. I always feel a bit sorry for the little kids sitting on the grass while blokes in their 40's take over the ramps, but my point is that it should be big enough for everyone to use. Folk always moan that kids aren't active enough these days yet the council stopped them skating outside the town hall in Crouch End where there was plenty of room for them to do so.
