I've noticed that the further east you walk along Lady Bird Lake, the more industrial/neglected the area looks. The boardwalk is beautiful, of course, but I've noticed that the areas under the overpasses are littered with junk (such as an abandoned baby carriage?), which makes me feel a bit wary to walk around there.
As a way to brighten up the area, I would love to see some local artists decorate the concrete pillars under the overpasses on that side of the lake. I think it'd be a great way to draw more people to explore that side of the trail, and make it a uniquely Austin spot. There could be spray painting works of Texas wildflowers or something uniquely Austin-y. I just think it would be a great way to liven up that side of the trail and capitalize on showcasing some great Austin artwork.
