As I said, the bus is primaily used for gigs farther away. The local gigs are generally at places too small to park the bus. Well I can always park it, but it borders not being worth the hassle when you drive only 20 miles.
My friend, we are all in the same boat here. You don't have to make any excuses...you're a busnut. You will spend gobs of money on an instrument of torture that will bring you some small measure of pleasure while others just stand and scratch their heads. Sometimes, you will feel the pangs of guilt and ask, "what am I doing with this thing?" Just take a deep breath and that feeling will soon pass.
I used to drive my family to a restaurant just 11 miles from our house. Drive around for 30 minutes to find a place to park, walk three miles to the front door, grinning the whole time!
