I remember the first time we discovered one spring about 6 or 7 years ago, there were a bunch of new baby ducklings with their moms swimming around the Rivers of America in Disneyland. We spent a good half hour just watching them avoiding the oncoming boats. I don't think that's the only thing I'll remember from that trip, but it was certainly one of the highlights. I recall reading recently in something like Mouseplanet or another site that this happens every spring and some of the annual passholders will come out to watch the new little ones.
Then on the opposite coast at WDW while sitting on a bench at the Coronado where we were staying, I remember watching the cranes fly over the water. My most peaceful moment at WDW.
Here you leave today and enter the world of yesterday, tomorrow, and fantasy.
