In an ideal world, I'd love for the waterfront to complete the loop and for a separate line to go along those tracks. Have it start in Lakewood near the Gold Coast and follow the tracks east, diverge to stop at tower city, then continue along the waterfront line tracks, but branch off and keep heading east along the shoreway all the way to MLK. It would definitely support development and park usage from Edgewater Beach to the downtown lakefront to Gordon Park. Maybe throw in a mostly direct bus along MLK from the Gordon Park location down to the Cedar University station to tie it all together with the red line and University Circle.
In an ideal world...
