Sod that "nature" reserve!
I used to cycle to work through that swampy dump, all i used to see were mosquitos, nats and the odd seagull!
Plus lots of men dressed in camo gear with cameras the size of a small cannon! (i guess large lenses are required when photographing mosquitos at 100 yards!)
I used to get cursed at by them, as "my cycling on a footpath was destroying the nature reserve"! (It was either through the nature reserve or along the 4 lane A27)
Flatten it, build a nice big (cheap) marina with a giant RIB shop and a petrol station offering half price petrol to RIBs.
