D.P.
Well... spobably not because there are usually too many other activities going on that day -- but maybe because less people are traveling this year you would still have a good turnout. The key is good advertising and easy to read signs that are well placed. If we were going somewhere and had time, I might want to stop (especially if I saw that there was kid stuff). Make some great signs and the more neighbors you can get in on it the better (we really like to stop when we can go to more than one or two sales very close to eachother). Advertise on craigslist as well as put up some great signs. Good luck!
