Rode the Singletrack twice this week (Thursday and Today, Sunday). Trail was in good shape. A little sandy in spots (mostly mid-turn) the first few miles but great after that. Fun fast trail without much climbing or technical stuff.
I really wanted to hit Arcadia today on my way back downstate, but I didn't have access to a GPS, didn't have a map, and forgot to write down directions from Traverse City. Hopefully the next time I'm up there I'll get over to Arcadia.
