We have gotten Drake on the road to be cart trained, but we only took one class. I don't know how many he has to take to be certified. He took really well to it and I want to build a cart soon. I'll have to dig up some pics, they are so cute! As for the water training, we haven't done any "official" work, but we take him to the water and have him retrieve constantly and "save" us while he has the energy to do so. But no boat work yet. It would be fun to get him certified later on, but before he gets too old. He's going to be 4 next year, I can't believe it!
