A few ideas and very appropriate for the times:
I’d definitely follow the “Stay at home” order more closely. I could be a model citizen with a beautiful tank. With another big tank I might never leave
I’d finally remodel my office and build a tank room
I’d kick my 21 year old out and use her room for the ultimate tank setup.
I’d use that dive certification for a trip to Malaysia and get and HG
I’d ride my bike across the state... I’d ride a mile for every gallon the tank has.
I’d volunteer to do reef restoration
I’d volunteer for all Reef2Reef events
More ideas to come!
