Thank you for the congratulations everyone . I am remarkably proud of myself, because I didn't really think I'd get this far (thought I'd just end up giving it up).
Agalch - I just go round and round the fields behind our house - it's not very exciting, though pretty, but while it was fine while I was not getting very far, I think the time is coming when I'll have to brave sarcastic wolf whistles and cars hooting at me to make me jump, and get out on the streets.
TigerFeet - I have had to stop MNing at work, because a colleague mentioned that someone had asked him whether I had enough work to do because I was 'always on the internet'. I took it as a timely warning, and have barely MNed at work since.
