Hi Steve - ta for the invitation to the opening of your ruminant residence...assume you don't want anyone who's easily "cowed", ho, ho. Gonna try and make it to this, but it's right in the middle of the fortnight I've got booked off work, so it could be that I'll be away with 'Er Indoors (or even on me own, cos in this uncertain world, nowt's constant, is it... well, we can only hope )
