This fall, could you get a bunch of pumpkins and then on the weekends at certain times drive through your neighborhood selling pumpkins kinda like an ice cream man? While you ring a bell or something like that.
Or maybe even have a yard sale that just sold pumpkins and mums? Would that give you a chance to meet up with local residents?
Could you even go door to door and hand out gourds with a postcard sized ad attached to it with a ribbon?
You could leave the trailer out in front of your house with a sign that said pumpkins $.50. On your honor. Maybe that would attract attention too?
