yes my father was a chameleon so it's very easy for me
if people are struggling then they can splash and dash at Kielder (just dont look at the prices) ooohh which brings me to a point, the station at Kielder is unmanned and card only.
ermmm urine stops, well any convenient tree along the way will be just fine but the only real loo will be at Hartside cafe. dont worry though as i'm sure that you will have the urine extracted from you at each stop
