There's an old streetcar that ran between Lake Como and Lake Phelan, Though rather than going straight like Wheelock park way does, It went down Dale, and At Summit started a steep decline into downtown St. Paul (plummet), before following E7th street and climbing the Bluff, proceeding up arcade and Forest streets before reaching its terminus at Lake Phelan. It seemed odd to me that something might plummet before it got to the bluff, but if you follow this track (11 on the map) - couple with its circuitous rout and starting and stopping like a streetcar would it seemed to make sense.
Once at the summit, it did quite plummet
Before it got to the bluff
Starting and stopping, winding and hopping
It will eventually lead to the stuff
