I can join you. I usually head out pretty early. Might have to turn around and be home early. We can hit Tomin no Mori or I have another route that takes out near Okutama and on the way to Chichibu. Don't have to go that far it is about 180+.
Where are you coming from? Where would you like to meet? Usually on the west side, Tamagawa, we meet at Ys road along the river. Do you know where that is? Also, I usually meet some time between 5:30 and 6:30. But depends upon where people are coming from. Let me know what time works for you.
