I could have dropped $1,000 if there was something to buy.
There was one display with quad/hexcoptors which was good, but they didn't have anything for sale. I would have gladly purchased a high-end kit (unlike the Parrot Drones I bought my kids) if they had some ready to go. Likewise my kids were expecting daddy to get them a maze/line following or similar robot kit. Again, nothing really interesting I could buy on-the-spot and take home to play with. Perhaps I should put a booth in next year and make sure I've got lots of kits ready-to-go.
Meanwhile, if I was into arts & crafts there were numerous booths with stuff for sale.
Oh, and the entry fee was high. $46 for me and two kids is way too much for what they had. Well, maybe not. The hotties trying to outdo each other on the hula-hoops was a brief high-point.
