The range is not open 24 hrs. It usually closes at 5 pm other days at 8 pm, and also has holiday hours if they aren't closed for a specific holiday. Does anyone know their true hours?

For public use, the range is open dawn to dusk 7 days a week 365 days per year unless there is a tournament or event going on that closes the entire range. That, however, is rare.

Literally sunrise to sunset, so it varies a bit depending on thr season.

The hours are from sunrise to sunset.

does anyone give lessons?

So clearly 24 hrs as stated on Google is WRONG.
