Happy St. Patrick's Day! (carrick-a-rede rope bridge)
I walked this rope bridge in County Antrim, Ireland, and mid-way it has an incredible sway. By the time I took this shot my legs felt like rubber-bands. The woman at the far end took three steps and froze; someone came and talked her back. There's about an 80' drop to the water below.
(they've modified the bridge, in recent years, to make it safer)
