I've lived in this area for nearly 6 years and driven by Mr. Ed's many times, but never took the time to stop. This is definitely a low-key activity and that's what I like about it. It's also FREE, which never hurts. You can't even begin to take in all the elephants in the collection. They are mostly concentrated in one long room, but there are other bits around the rest of the store. And it is mostly a store, with all kinds of candy. Many other touristy items for sale, too: shot glasses, t-shirts, ball caps, etc. Fun things to gaze at out in the garden area, too. The flip flops hanging in the trees along Route 30 are a favorite landmark for my daughter on her way to/from camp.
You don't need to budget a lot of time for this stop either. Could just be a convenient place to stretch your legs and get some candy. We stayed about 20 minutes. I'll be back. Just for the heck of it.
