We ended the afternoon with a newish side tracked at shrivenham. A cleverly hidden cache, but soon found I was on private rail track ground after a worker turned up.
Him: what you doing?
Me : having a rest from driving and stretching my legs? Why what you doing?
Him: I work for rail track and I believe you're acting suspicious.
Me: what watching for trains, is it cos I don't have an anorak on?
Him: no its just you don't look like a trains potter and this track to the gate is private rail track land.
Me: I'm sorry but never saw any signs, but heyho I will watch them from my car instead.
Which I did and after a few minutes he went and I got the cache. Looks like I'm afraid to say this one is on private land, but certainly a cleverly hidden cache.
