Late Thursday I sent an email to Jim Kearney at Planet Bikes, and copied you, on an outline for the day, and I called Jim to verify that he received it. Here's the lowdown, it's still subject to adjustment if the Dubois people have suggestions.
Sunday, September 19 - Pittsburgh group to meet at Schenley plaza, LEAVE at 9:15 am., arrive at Dubois meeting point at 11:30 am +-.
Dubois group to arrange a meeting point (other than the Ghost Bike location) and a route for a slow 5 mi+-/30 minute "Ride of Silence" to the location of the Ghost Bike placement. Depart from meeting point at 12:00 noon. Individuals to bring and wear simple black armbands in remembrance.
If individuals are unable to ride or uncomfortable with road riding, an associated automobile/motorcycle procession is welcomed. We want to work to the true spirit of "Share the Road". Interested individuals or Dubois group should check if a permit is needed for something like that.
Ride of Silence to arrive at Ghost Bike location at 12:30 pm., brief memorial, 15 minutes +-
FYI this is not our website but it is the inspiration and explains the concept: http://www.rideofsilence.org/howto.php
We will suggest that people bring bag lunches or something. After some time for lunch, I also ask that the Dubois riders set up a little recreational ride after (not "silent"), 15 - 20 miles for those who may want to do that. Leave 1:30 pm. Maybe a route he enjoyed or something. I think that would be a great way to remember this gentleman, and also move forward positively and joyously, as Dr. Varacallo seemed to live.
