I have some reservations about doing this.
1) A plain A5/A6 sheet will turn to mush and be a pain in the backside if there's a hint of rain.
2) Putting a flyer under someone's windscreen wiper just looks like a cheap advert for a poor product. Or like a message from Barryboys.
There's nothing stopping people from doing that, but it'd be nice if we had a consistent, well-written message to leave people in a plasticised, business-card format like what Al uses at shows on his own car to advertise his graphics service.
As rare as we are now I'm not sure how many of these would be given out, but I think it's something we could look into for members and be funded by the club.
