Vicarage farm is very friendly for a first go, no horrid water like Pachesham they dont have the dates up for 2011 on their website yet but im sure it wont be long.
If you're on facebook take a look at www.facebook.com/unaffiliatedxccoursephotos - I set it up so people could see full cross country course photos before deciding to enter an event
I only have photos from the 70cm course at Pachesham in Surrey, but have photos of a few small courses in Kent that might be of interest, and will hopefully have more courses added as the events start again this year
