What a city. I had the opportunity to work in this city in summer a couple of years back. We arrived in the city the day after the Brickyard 400. Which is one of the races in the NASCAR circuit.
The downtown area of Indianapolis is very people friendly What I mean by that is there are plenty of places to eat and entertain yourself, no matter what entertainment you are looking for. There a restaurants at all price points, movie theaters and hotels. The city was easy to navigate. Which is odd, considering the person they called to help design the city.
Alexander Rolston was the designer, who assisted L'Enfant with the design of Washington DC. By contrast one of the more difficult cities to navigate.
The city has also hosted the NFL combine for the last couple of years at Lucas Oil Field. (I believe that is the proper name).
I found the city to be very clean for a downtown. The entire city supports the different events that happen there, even in my hotel, there were racing items.
The city hosts an Indy Car race also. Maybe you have heard of it, The Indy 500.
Have a great day.
