Curious how the different users of access, stumble over each other and manage to fall out. This reminds me of an open access area of Nescliffe in Shropshire being opened up, it was decided to make all the ways dual purpose, therefore Bridleways. I've no doubt it seemed a good idea at the time, one of the members of the body that administered this area, had served with me on many NFU committees way back in my farming days and he unburdened himself over a few pints by describing the complaints and counter complaints between the two fractions.
Having spent 45 years organizing horses at the County 2 day agricultural show I spotted the root cause. Firstly the area is sandstone with good parking, so horse boxes could bring in rider from a long distance, especially bad weather. Second the horses hooves would cut up the trails and cause ever increasing puddles, and thirdly the walkers would walk around these and tread out the bramble and briars to create a new path.
Unfortunately there is a human factor that exploits these new dual usage and comes in the form of Miss Awfully-My'Pony later marries and becomes Mrs Awfufully-Busy at Coffee Morning Corner, has a horse box you-know. Sadly circumstance beyond hubbies control does'nt allow her employ a groom.
So Nag gets ridden onto any new dry pathway, (to keep its hoofs clean and dry) creating the grounds for an endless stream of complaints as the quarrel deepens and becomes more bitter between two types of access user.
