I've found that out-of-towners work the shops more than locals (and they leave a card where locals do not)...

There was a time when I used to advertise in over 350 daily/weekly newspapers and hobby tabloids' want ads; and in those shopping center rags... and it was mostly those type shops as you mention who would call me.

I also concentrated on a 100-mile radious of USPC hitting all the shops/markets where some of those malls would even hang my flyers on the walls for all to see...

The best part of this hobby is the harder you work the more fun you have...
