Dump Truck birthday party!

For my son's third birthday we had a construction party!  The cake was a dump truck holding dirt in the back.  I had made signs and put them up around the house.  I used black and yellow table settings.  And we played two games that my son just loved and kept wanting to play over and over again.  The first one was a construction site obstacle course:  I cut cardboard into stripes so they were kinda like boards, and we had some cones set about.  They had to walk the cardboard and go around the cones.  The second game was tossing little cones, that I picked up at the Dollar Tree, into the back of a dump truck.  We also had hats that we let people write on!
