Crisp air whooshing through vibrant leaves, raking sunlight picking out hilltops and shadowed rambling valleys.  

[Especially after a hectic week,] nothing beats a long walk on a perfectly unplanned fall afternoon when no other commitments alter the open-ended freedom and leisurely pace of the day--especially when something particularly charming catches your eye.  For me this Sunday, it was a scattering of acorns nestled along a stone wall.  Spotting those beautiful pre- oak trees felt like discovering a secret treasure hunt that nobody else knew about.
