Yep Dave, I am indeed , and only approx 20 miles or so from Ashdown, never ridden it , but know its a great place.
Sold my MX bike ( KX250) a few years back, and replaced it with a KTM EXC, altho I still have an ancient YZ400,it hasn't turned a wheel for many years.
These days I'm a green laner, just like the going off exploring thing better than blatting around an MX track , and well, truth is I'm an old fecker and don't ride often enough off road to be fit enough for more than a couple of laps of most tracks.... 
Off out this week-end with two Berg owning mates on an adventure around the Basingstoke/Tidworth/Andover/Salisbury area, just see how far we get, love that sort of thing.
On the off-road stuff, are you MX only or do you ever do hare & hounds or green lane sort of stuff?
