Field Notes
Saturday was a bitter cold day but since Blackie, my husband, and I had not walked in a while, we decided to brave it and go for a walk. We got out the mittens, hats with earmuffs, scarves, long jackets, and our walking shoes; we were still chilled, but with some brisk walking tolerated the weather. Sunrise Trail is a multi-use trail, paralleling old railroad tracks for a while, used for various modes of travel, including walking! I was looking for berries -- on barberry bushes or bittersweet -- since the day was dark and the path out of the sunlight, I thought they would be easy to spot. We stopped near the Kelkenny stream and took a few side paths looking for invasives; I did not find any. The trail is miles long, and I will have to return another day and start at another entry to investigate more of the area.

Good for you three for braving the December chill. Kelkenny Stream looks beautiful, and I appreciate you looking for winter evidence of barberry and bittersweet as you hiked.

It would be great if you (and Blackie!) could take a second look along this trail in the springtime as the new leaves and flowers emerge (imagine that, warmth and flowers!).

Keep adventuring, BHG! Stay warm.
