First of all let me give you a short introduction. I am actively engaged here in the UK on a new build (say it quietly!) standard gauge loco project, and am most unlikely to be able to visit the C&T even though I have a great interest in American narrow gauge. I do however keep an eye on your most excellent web cams and have spotted lots of wildlife earlier last year. What to me looked like a porcupine passing the depot plus a fox and deer in the loco yard. The reason for this is that I often view early in the morning (UK) time, so right through your night past midnight into the early hours. My final point is that those of us abroad may well be an extra level of security for your site, so please do not close down the depot cam to the outside world.
Wishing you all the very best for the New Year,
Fred
