Was nice out this afternoon, so I took my bike up to Groveland. Rode through Groveland to West Newbury, then went east along the South bank of the Merrimack into Newburyport. Crossed over to Amesbury on the famous (but newly rebuilt) Chain Bridge, then rode back along the North bank to Haverhill and Groveland. Saw a couple of lonely-looking Bison at Kimball Farm. It got chillier and darker as I went along, but it's always a beautiful area to ride in.
