Just FYI, but there is a small section of construction walls up to the left of Camp Jurassic entrance (at tail end of the old Triceratops Trail lot). And I heard drilling/electric tool noises coming from behind Raptor Encounter last night. Don't know what might be going on but thought it was worth noting.
Also, some new JP keychains are available at the giftshop and one of them features a baby triceratops and says "Jurassic Park Petting Zoo" on it. The image looks like the small puppet/animatronic they carry around so probably just based on that.
I'm not saying they are building a version of the "Gentle Giants Petting Zoo" in the back half of the old Trike Encounter plot... but damn that would be awesome.
