I have left for years at a time. Sometimes you just get bored with them. In 2009 i had 27 machines come threw m home be shopped played for a few weeks and then left. I got burnt quick. I worked for a op and pinball got old fast.
Now i always like pinball but sometimes you walk into a room turn on the light and say F*ck i could have a new Vette and i sell all the machines.
I raced My Datsun on the scca circuit for years and pins where not gonna buy tires on my datto or c16 in the tank so pins had to go then too.
