Sunset on July 22 in Sioux Center will be at 8:56 PM. At a leisurely pace of 15 MPH the trip to Oak Grove State Park and back would take 2 hours. Figure 30 minutes to dip your tire and take a picture… you’d have to leave Sioux Center by 6:26 to be back before sunset. I don’t know what time PBV will drop me off in Sioux Center… Do the charters arrive early enough that we could pick a meeting point and leave at, say, 5 PM? Or earlier?
