I am not sure how many sponsored egg hunts will happen on Easter Sunday (due to the holiday and all)... but here is a thought. You could have yourself or your husband go to a park or playground near your home about 30 minutes ahead of you and your children and hide eggs all over the place. Then when you get there, you can have a hunt of your very own! It's more work, but would be fun!
We do a hunt on Easter with our family in the backyard or a nearby park (about 28 of us or so with kids included). We all bring our kids' Easter baskets (empty) and a bag of plastic eggs filled with Cheerios or Goldfish for the tiny kiddos, and candy for the bigger kids. A few of us take all the eggs and hide them outside, and then we let the kids out to find them! The young kids' eggs are in one area, and the big kid eggs are in another. We re-use the eggs every year and it's become a wonderful tradition. We even did it in the snow one year! The eggs weren't very hard to find that time! :)
I wish you luck - I think hunts are advertised in the paper at some point... maybe check online as well. Watch for signs posted around your neighborhood as well.
