There have been many times I’ve been tempted to temporally borrow one of the zoo keeper bikes at Barcelona Zoo, just so I can get to see all the enclosures before it closes!
You often see the keepers zipping around on them, leaving the golf buggies to the security guards and visitors. I love how each animal classification has it’s own dedicated bike often with a makeshift plastic box back pannier. But I don’t get the locks. How can someone walk out the zoo through turnstile gates with a bike?!
