Many smaller or more heavily developed zoos would find them difficult or even impossible to install, as although not especially heavy, they are cumbersome to move, needing a sizeable crane or a couple of large telehandlers.
Indeed - I imagine the only reason they are a reasonably feasible option for yourself is the semi-rural location of Hamerton and subsequent relative ease of access to heavy machinery available to the farming industry?
Somewhere in the suburbs, away from wide open fields and constrained by surrounding development, would struggle to find this an option I assume.
