(knocking on wood loudly and constantly...)
So far, we have not noticed much of a downturn in the MI side of things.
Most (not all) of our dealers are holding the line on sales, some are actually reporting an uptick in sales!
All of my industry reading is reporting that sales are steady to slightly brisk for MI.
As tycobb points out, live music in the right location will actually tend to see an upswing, the one thing that seems to go up in recession/depression (of the economic variety...although it can be true of other versions of depression

) is drinking. Not saying it's a "good thing" overall, just a fact.
I hope that things don't change much in our industry, and hopefully this will cause a renewed interest in LIVE music as folks tend to keep closer to home and spend their leisure time (and $'s) on nights out one or two times a month instead of saving up for long and expensive vacations. Hopefully, the "neighborhood bar" will make a comeback and give us good venues for live local music again...
It's all a matter of looking for the positive side of things, and then working toward them...
