TCSidewalks Live: Saint Paul Alleyway Spelunking

If you're not doing anything this Friday (tomorrow), join me for a trip down the alleys of Lowertown / downtown Saint Paul. We're going to explore as many of them as possible...

6:00pm, tomorrow 7/5, across the street from the Gopher Bar.

See the Facebook invite here.
 

What is in these alleys?
What could be in these alleys?
Are there any alleys that actually serve as through alleys?
What does it look like to travel the city via alley?
How many blank walls are in the alleys? Must they remain that way?
Who is the alleys?
What are they used for?
Which are cut off? Must they remain that way?

Etc. etc.

All pertinent inquiries considered.
