Glad you'd be interested Hobjob pal
As for the Raft Spider- it's great to know that it exists elsewhere. I did not know that, but now I do, I'm happier! There's nothing scheduled as of yet, so I mean if people say when they're free or suggest dates to do it? It's never going to be a problem for me to do- I'm no more than 8 miles away from it. I presume weekends are best- so one weekend at some point in summer sounds good.
