You have to sign the folks up before you can debate the customer value proposition vs. training methods.
An excellent point.
Interesting that when locked up, folks went fishing with lots of newly purchased gear.
Well, as long as they don't have a European style lockdown, you can easily find a fishing hole nearby to fish almost anywhere in the US. You don't need training either. For some, just drinking beer all day out in nature makes for a good day. Gives plenty of time to come up with stories on the one that go away.
If they decided to dive locally they sure didn't buy much new gear.
# of fishing opportunies eclipses the number of dive spots.
Plus the barrier to go fishing is relatively low.
EDIT: I'll add that the overhead for fishing is also much lower.
