Alex and I took a trip up to the Leelenau Trail on September 20. It's a 15 mile trail stretching from Sutton's Bay south to Traverse City. This trail follows a former rail line, so it is very flat. Most of it is asphalt-paved, but there is a stretch of crushed lime.
The weather was great - highs in the low 70's and partly sunny. A little rain in the morning, but cleared up by 10:00am.
