In reply to GerryC:
I have only been walking three years but in that short time petrol has gone up from about 1.05-1.10 to 1.35-1.40.
Back in that first summer myself and a mate decided to do some weather chasing and drove from Dundee to climb Beinn Alligin and back again the same day.
Apart from being bloody knackering I just don't think i could justify the petrol on that these days. Instead of walking every weekend now I'm more likely to go once a month, camp up somewhere and try and get 2 or 3 walks in over a weekend.
Having said that I was up ben More and Stob Binnein two weeks ago and it was like a fair, must have passed close on 30-40 people, so the accessible hills are probably as popular as ever.
