So your "yesterday would have been the 18th. If you were in Denver, that would have beeen PRIDE weekend so maybe they were practicing for the parade (which was the 19th) and that is why they were on the lawn in whatever garb and parasols.
Next month is rodeo month, they might all have on cowboy hats. Getting cold feet is common but unless you contact the group there may always be an excuse to feel wierded out. Not everything you see is as it is
