Yes, we have printed info sheets that we hand out at Equine Affaire mostly, with general mini info and links. We have offered to take minis to Newtown CT and they have contacted us, but we are in no hurry and must wait now until all foals are on the ground.

I will likely keep thinking of things). This one may be a bit strange, but we enter our minis in photo contests run by "big" horse magazines, national sponsors or even local papers. Our 2012 colt Clyde came in third in a contest last year sponsored by Dressage Today magazine and he not only won 1/4 ton of grain, but a lot of people got to see his photo. I did let the magazine know that we plan to train him to drive in the future, so he will be expected to compete in dressage some day. I just submitted an essay for another contest last week.
Now, I maybe shouldn't mention this, but all this promotion has not helped us one bit in marketing our minis. We have not sold any of our minis that we have offered for sale over the years. Can't compete with free or Craig's List.
