What ever the angler is willing to pay

My Old man has coarse fished all his life, (now in his 70's) When I tell him I often spend the best part of £40 on a days fishing he has to sit down for a while.
Each water whether Still or River, South or North, home or away has its own unique experience, that is why we dont just stick to one place, so for me I am not just paying for the fishing I am paying for the experience of that particular water.
Would I pay £150 for a day on a chalk stream? Probably for the experience, but most likely only once. I went to the Hebs for a week this summer and had a cracking time, would I go back? No never their are so many other places to experience.
Also some thing to concider is what money is worth, £150 is alot of money to me, to others on this site I am sure it is loose change.
So like I said, whatever the angler is willing to pay.
