I'm still a member, and its not exactly expensive but I'm not surprised people aren't renewing. A big thing for me is the Saturday day out to Hampden, but there's hardly any of those now due to the fixtures (fuck this Friday night football shite). And you don't have to be a member of the SSC to get a ticket these days, they should have reverted back to 2 tickets per SSC member.
Booth and Mason were my favourites from the post-Fergie era. I too was gutted when Mason left, he was such a brilliant footballer. I was gutted when Booth left but very pleased when he came back for his final spell and was a much more cultured player after his European experiences.
Mackie? Paul Bernard? These are nowhere near being the worst players to pull on a Dons jersey.
I echo Dave Min's comments about it being way past the time Mackie moved on though.
