Which way's up?

How many times have you picked up a harp and started to play and it was upside down! No doubt this is an embarrassing moment. What's the simple answer? What do all the pro's do? Every time you pick up your harp give it a little puff on the bottom (left side) of the harp. If it's low, you're good to go. If it's high, flip it over and breathe a sigh of relief that you're a member of BluesHarmonica.com :-)
