Welcome,
Been up to Glentarkie a few times, fantastic, not too sure if your Freelander will have the ground clearance for some of the runs as they get rutted badly so take it easy, Defender / Disco are ok, there was a Mitsubishi shogun belly stuck last time i was up and we gave him a hand to get sorted eventually winched him off.
The club runs great green lane runs roughly once a month, Alan (yellowdisco) is the Green Run Guru, keep an eye on the callander, next ones in December. We were at Keilder recently and it was brilliant, Carron Forest was last week and it was pretty good as well, there's nothing to stop you heading off down to Keilder and doing the forest run yourself as its normally open, just £3 at the barrier and you have acces to miles of track, great day out for everyone, take a picnic and a OS map
Hope you enjoy your Land Rover
Jock
