[Raak] I would love to hear more. When I worked on a national newspaper many moons ago - they sent a group of us on one of those weekends. If I remember correctly, it was a hoot. I'm wondering if 2003 methods are less ... ahem ... aggressively american.
[Btd] Well, I found it worth while, though it would really be up to whoever knows me to judge the effect, if any. [Chalky] Do you remember what group it was? There are a lot of these things (perhaps less so now than ten or twenty years ago), and yards of self-help books in all the bookshops. I expect that Sturgeon's Law applies. I'll write more when I have time this evening.
[Boolbar] If you put the doors up first, you can then shut them and therefore won't have so far to chase the mice. Also (if the mice co-operate) can the chase not be part of your workout? Could you persuade them to run at half-pace for the first ten minutes, then full-pelt for 15 minutes, then a cool down pace for the final ten? It would seem to be the organised thing to do.
