Thank you to all who answered my question about spending a day in downtown Indy alone while my husband was in a conference. I wasn't able to do everything, but I had a wonderful day and so appreciate everyone who took the time to post. I found Indy to be a great city, very clean, attractive, interesting and walkable. I felt totally safe and comfortable as I explored on my own.
I loved the Soldiers and Sailors monument---very impressive and interesting! The small Eli Lilly Civil War museum in the basement was nice, also. I walked to the capital and went inside----beautiful! Then walked to the canal walk---what a great place in the middle of the city! Enjoyed strolling to the park along the path, then went to the Indiana State Museum. Learned a lot I didn't know about the state and its history (but not why ya'll are called "Hoosiers"), then decided that since the weather was so lovely I would not spend any more time inside and so continued my walk on the canal walk, enjoying observing the paddleboaters, bicycle surrey riders, a wedding party posing for pictures, and spent some time in the wonderful Medal of Honor display. Finally, I went back downtown and walked around, ending with a treat at the South Bend Chocolate Co, sitting outside and people watching.
I'm so glad I came along, and will look forward to visiting some of the other points of interest that I missed when we return next year.
