Slightly off topic but I read a link which was posted on a certain trip where alot of good suggestions were made towards the end, I was wondering how close if at all these are to be implemented.
The simplest solution I would use is to not use dates when issuing permits instead allotting a certain amount for example only have 52 for the year therefor no matter what the weather is doing you can go when it suits you (provided it is not in closed season or dates stipulated when no caving is to be done).
You could have a meet for certain trips only to have the weather cancel your plans and send people back home or even worse. chance it anyway, as you may have to wait another 6 months to get another one.
The issue however which blows my above idea out of the water is, whats to stop people re-using the permit. That is the point that the below may cover.
Maybe you send an e-mail on the day or night before when you know your trip is going ahead. When you send the e-mail the e-mail it effectively counts as you have used the permit. If your in the cave without sending that e-mail even when you have one of the permits it is like caving without one. The land owner/farmer could have a copy of these e-mails if they want to check on people.
I know this system works quite a bit on trust but dont the current system too?
All you need for this to work is excel and a list of clubs and e-mails. To make it even easier someone could build an application that does most of the above automatically, but that would be further on down the line.
Just an idea, post your none flaming thoughts.
P.s. If there is an unlocked thread this should be posted against feel free to move it there.
