Fun thread. I agree people in Ohio need to be more proud of Ohio and stop treating it as a punchline. IMO, The coolest part of Ohio is that opportunity abounds for young people. 'Owning' something tangible (small business, real estate, education, etc.) is much more readily attainable here than in other big cities.
Otherwise:
1. Obviously high speed rail would be awesome for Ohio. If a true HSR system is built from NY/DC through Ohio to Chicago; Columbus/Cleveland could be a 2-3 hour train ride to Chicago/NY/DC/Philly/pittsburgh etc. What a huge growth asset for Ohio cities.
2. Celebrate creativity: art/architecture/science/tech/etc.
3. Make 'sustainable' efforts more visible
4. Create distinctive parks and public environments.
5. A few more wacky new buildings mixed with our awesome historic architecture
6. Play up our many, many outdoor recreational opportunities (biking, camping, kayaking/boating, hunting/fishing, golf, etc.)
7. Local Food
8. Industrial heritage is cool looking
9. Ohio has 'REAL' and rich history.
