Drive-through Busking

I've discovered a new concept: Drive-through Busking.  In Corpus we have drive-through Starbucks, MacDonalds and all the chain restaurants.  There's drive-through beer and drive-through prayer.  So, why not busking?  Pull over, roll your window down, I'll sing you a song.  Here's the sign:

That ought to get their attention.  My wife was my first customer.  She pulled over, rolled down her window for me to serenade her.  Of course, she tipped me generously.  The merchandising with this business venture will include gift certificates, of course.  Not sure if it's legal, but we'll see what happens.

Of course this is all just in the planning phase at this point. 
Busking in Corpus is pleasant in the winter.  It was in the 70's and 80's this past week.  No need for handwarmers here.  Fond memories of busking in Philadelphia in the winter.  Thank goodness for the heated subways.
Anyway, I had a surprise the other day.  A food truck was parked right in front of where I play.  Food trucks are loud with their gas-driven generators which are as loud as power mowers.  Why can't they cook with quiet bottled gas?  Anyway, I gave up competing with the noise and moved half a block down.  Actually this turned out to be a blessing.  Shade, quiet, good acoustics, closer to the food court. 
Things happen for a reason.  I'm in busker heaven.  Drive by for a song.  Roll down your window.  I'll even supersize it for you.
