DCMOM...I have that same green mountain thing for cars....I also see your is missing the yellow looped track too! LOL!! My kids ripped it off immediately! They sell replacements on e-bay for like $14 but I figure they will just rip it off again so why bother....
Nice set up you have going on. I love your wooden old school kitchen center...I hate the plastic ones they have out now...the wooden ones are durable and I love them!!
