Thank you both, must admit to never having heard of the clayjar thing so thats new, I know what you mean about the "significant hike" icon it would be good however if that was on the main listing page so you could see it immediately along with the distance from home etc.
As to the other comment about stringing them together we do do that, we have a gps/pda and have all the maps for the uk down to footpath level so can generally make a good hike out of it, its just nice to not have to plan them out all the time not knowing if its a nice walk, cachers have given us some lovely walks over the last couple of years of which we are grateful but there are so many exceptionally short ones to sift through first, still never mind, a very small issue on an otherwise fab site.x
