I've been to Epping once, a long time ago. It's quite a fun area.
That was Epping North, back in November I presume. I didn't think that was a great map, certainly not quite as fine as the other Epping areas, although still nice and technical. There was a bit too much dark green on it. Epping South West and Epping East are the best of the four or five mapped areas.
Yes, there was quite a lot of green on the map, but the course I was on didn't go through too much of it. So I have good memories of the place. =)
