Colorado: cities, venues and capacity
The Colorado picture for an organizer — 259 venues across 21 cities, ranked by what the record can prove rather than by marketing copy.
Empower Field at Mile High states the largest capacity in the state. The dots show what event67 would bill at that head count, and where the price stops.
What the record holds
Colorado is a state of United States of about 5.8 million people. Denver is the capital.
The mapped inventory comes to 16 exhibition or convention halls, 33 dedicated conference and function spaces, 36 arenas and stadiums, 39 theatres and concert halls and 135 independent event spaces.
The largest stated capacity anywhere in the state is 76,125, which is the practical ceiling for a single-room programme here.

Top of the capacity range
Ranked by stated capacity, then by how much the record can prove. Open data rarely publishes a capacity for a convention centre, so a hall may sit below an arena here without being the smaller room.

One more town has a venue worth its own guide
The town itself is too thinly mapped for a city guide, but the venue publishes enough to stand on its own.
- Breckenridge: Wheeler Opera House (503), Tabor Opera House, Silverthorne Pavilion
Also in Colorado, with nothing mapped yet to build a guide from: Westminster and Commerce City. They appear here rather than as pages with three facts on them.
