In past years, a group of the "early arrivers" gathered at the Chrysler Museum on Friday for a tour as a prelude to the Dream Cruise. Although the Museum in now closed to the public, the mansion built by the widow of one of the Dodge brothers is located across from the museum. Tours are available for $15, and this may be a good alternative for the "Friday Folks" prior to heading down to Memorial Park.
If there's any interest, let me know and I'll set up an informal Friday tour. Here's the link:
