I turned out of curiosity up the narrow Gemini Trail¹ past a decrepit cabin. I was curios about the history of the cabin — what was here so long ago? — but haven’t found any information yet. I went up a couple more switchbacks then turned back to Warnick Road. The trail is too tedious for motorcycle speeds, not worth irritating bicyclers.
