Sorry to see any dive shop close. But 31 years is a long time. Time to retire for some well deserved vacations. Here in the Chgo. area far away from any warm water diving. There are plenty of dive shops around. The new dive shop in town is booked all the way till the end of the year with OW classes. The 2nd dive shop is tripling its size with an indoor training pool to boot. Another 3rd dive shop that opened this spring seems to be doing just fine. With great website and internet skills they could increase sales more then what goes out the front door. More then likely a diveshop will have a new owner instead of closing up. It’ll be someone elses dream for the next 31 years. There is still hope for you to get a good air fill.
