In the past both 2 and 4 legged Smokeys have waited for the Volwalk at the top of the hill on Peyton Manning Pass about where Circle Park comes back in. No problem for folks to go out in the street with them for pictures. When the team got to that point, Smokey (and his handlers) lead the Volwalk down into the stadium.
They have said that the Volwalk will now start at the Torchbearer. I haven't heard exactly what that means (are they getting off the buses there instead of the practice facility?), but things might be a bit different.
As previously mentioned, Smokey and the handlers walk from the frat house to Volunteer Village, and many people stop them for pictures along the way.
