Wolfe,
There is an Islamic center less than a 1/4 mile from where I saw the first person and he was just on foot. The second had a bike, but the overpass was less than a mile from the same Islamic center. Do you know if there is an Islamic center near where you saw this? Was this between 32 and 100?

Today he was halfway between the footbridge at Columbia and MD Route 175. Last week, he was just south of the Route 40 exit off 29.
