But to police this new 4 hour limit properly funds must be put in place for wardens- hence the residential parking schemes. As you would know if you were "slightly more intelligent."
Given Preston Park Avenue would need wardens it's hardly much effort to pop over to the park. Regardless, if the Council procurement officer didn't get a fixed price contract with yearly reductions from the warden supplier then they need firing ( but given how useless council employees generally are I wouldn't be surprised ).
