£2 is nothing really, especially if its split between 2 or 3 bodies - and probably a lot less than the petrol cost of getting there for most travellers.
We have been at Seacliff a couple of times recently, and they charge £1 (as its a private road), ostensibly for providing a toilet / parking etc.
I cant see the problem. There was someone with a shop in Gullane on tv last night stating that this would lose them business - hmmmmmmm
Same topic, different spot -
We were up at Loch Lubnaig last week and parked the car for 4 hours for £2 (I think it was £3 for the full day).
This in the "previously unspoilt" (but actually full of lots of human waste) picnic spot halfway up the east of the loch. Its been tarted up with a little shop/camping facilites/bbq spots/toilets/bins - none of that comes free.
