I didn't know about the licence to "marshel" until we were asked by a local motor club to help out on a voluteer basis with possible recoverys.
When we turned up on the moors at midnight some busy body know it all mini hilter then started we needed this and that cert. and it came out some clubs (to protect them from claims) now require it.
But it back fired on them, we been pi****** off then went for a night greenlane run, only to find ourselves in the middle of a timed "car rally" cause been short of marshels had'nt sealed off all the row access to temporary road closures, not only us couple of local farmers needing access to there own farms got mixed up.
As for laning, well went south once thats south of Watford gap, and yea what aggro, loads of 4 legged dog meat animals with posh nob nasty bitches on top ranting and raving about we had no right to be there. Nimbies who spend all day ranting about how we are destroying there peace and quiet, should'nt buy a property on a road then.
Up here is queiter, most of the time never meet anyone, winter wet & cold like now is the best, yea some local "hotpsots" but list them on one hand, hardy any horses, bikes, and even walkers.
You might find other landy club event practices different, never known Marshels to be allowed to drive the course, even the competiors get kicked off for hitting them damm sticks, theres no freedom like some pay sites, all tightly controlled.
As for licence for Marshels, i emailed someone over xmas, but no one got back to me
