I've just found out about a competition; Bovril want to "spruce up the great outdoors" and are offering £100k for projects;

You have to do is set up a project and then vote for it.
Any use to Sydenham or the local area? I'm unfortunately not offering to run it! But there might be someone out there who wants to...?
