You must have loved the parade of mothers watching you trying to inflate the tires barely trying to hide their “this will never happen to my conventional wheels stroller” grin
Note that the Cameleon Bugaboo does NOT have air but foam filled rear tires, so they don’t carry a pump any more.

I understand you did have a faulty pump …

At any case, one of the reasons all-terrain strollers are commonly rejected is the risk of a flat tire.
I tell parents that this is not a car or a bicycle which you cannot drive/ride, but a stroller you can push (a little harder) and get the wheel fixed.

At any case, my 7 years old all-terrain stroller (OEM for InSTEP Safari) had its first flat tire after more than 7 year (and 3 kids )

Congratulations and Best wishes on your 3rd !

BTW, which stroller did you choose for this Zoo trip ?
Baby Jogger City ? Bumbleride Indie ?
