Hi Steve,
The skatepark itself isn't actualy lit, but on a Tues evening there are people on the astro turf pitch just behind the ramps and that does an ok job of lighting the ramps. not everything is rideable but most.
Check the roof of your car before heading over there though, if the roof of your car is damp then that's a sure sign the ramps will be fooked too, as they turn really quickly as are not filled underneath
Send me a PM if you do decide to go as may come and join you if you don't mind as it's only 5 mins from me
