I presume in order to stop them being overused and then stopped.
Or to stop some newbie turning up freshly armed with a GPS Tracklogger, recording the route and then advertise on sites like UKGSER to lead guided runs around £20 to £40 per person.
It takes a long time in County Council offices researching these old roads and I do get reluctant to 'give it away'.
Once a rider has attended a few of the runs lead by myself, for example, and I see that they are capable of following the code adopted by the likes of the TRF, GLASS or CRAG-UK, then my guard relaxes and information is passed on.
Another quick way of getting into the swing of things, is to offer your services at a Horse Trial/Endurance event, or a lane clearing day. You know, put a little more in, not just £40.
Timpo.
ps. I have not been a member of the TRF whilst using the UKGSER site. But, I (and Sarah Teach) have rejoined for the 2008. Nevertheless, I have been leading one or two trail rides advertised on this site, none of which attendees were charged or asked to make any monitary donation, yep that's right, all totally free of charge.
