Went for a CYCLE today, 30+ minutes.
Did some more exploring of the neighborhood on the other side of Alter in Detroit. The Hare Krishna/Fisher Mansion is less than 8 minutes bike ride away (good to know since the Rowing Club that meets there has beginner programs for the boys in the coming years). Also found a pretty, well maintained neighborhood that is an 'island', being surrounded the the canals to the river.
Perhaps next week I can see if I can cycle to the Manoogian Mansion....
