While in Philladelphia we didn't see the historic spots downtown, we toured the Martin guitar factory just north of Philladelphia.
It was a much bigger operation than I was expecting.
Guitar parts were everywhere.
I loved all of these clothes pins used in this step.
They have a mix of automated and hand work procedures.
The on site museum was also interesting. You can get a taste of the older ways of making guitars and see some pretty fancy custom work.
I couldn't resist a little costume bling.
If you are ever in the area I think it's worth a stop.
