people who have set ideas and won't get off their high (rocking?) horse to listen to other ideas....

Yes, well, that's certainly me. But if any crank has the least bit of evidence I'll get right off my horse and listen loads, but they never do. How is that wrong?

“Grants awarded”...”Careers built” Aye..Heritage Lottery is where it often comes from to revamp some established sites visited by the public. It’s a shame it has to be from the proceeds of gambling...and then they get you to pay again! Jestin’ obviously these places need constant income streams to keep going. But sometimes I don’t think they should build themselves up so high in the first place? Dunno..
‘Things’ can get ‘overlooked’ if it brings the tourist pound in. I’ve seen new museums built on what you might call ‘false foundations’..
I’m sure it’s only a fraction of cases but thats still too many. (Without checking the ‘facts’ I’m keeping my options open by saying ‘a fraction’..!)
I realise you weren't specifically referring to visitor centres..but Time Team and Visitor centres are the closest the majority of the public get to Archaeology. Not knocking either..
