Unfortunately for me, I've gone from feast to famine in the last couple of years. Sportsman's Outlet in Humble is near my home and still has not reopened from their fire and now Top Gun, near my work, is down. The range "in-between" is the 59-Gun Range and it's not a pleasant place to visit.
Have no idea what the financials are behind running an indoor range, but it seems like it could be a profitable business. There are quite a few anxious customers looking for a place to spend their hard earned money.
