UPDATE: (as of 8pm CST March 12) According to the Rowe Sanctuary site:
We are currently experiencing technical problems with the Crane Cam and there will not be a broadcast tonight (3-11) or tomorrow morning (3-12). Please stay tuned as we hope to have it operating tomorrow evening. Thank you for your patience.
Also, it appears the link has changed, so the link has been updated. The Crane Cam seems to be working as of the time of this update.
Thanks to Sue for bringing this to my attention.
UPDATE: (as of 4PM CST March 13) Looks like they have changed the link yet again, so I've updated the link again. If my link does not work, go to Rowe Sanctuary and click on their link.
