A sport ball arresting structure may be characterized in one aspect as including an infltable quadra-pod mounted on a substantially rectangular flexible plan ar base for placement on the ground. The quadra-pod includes four legs formed, when the quadra-pod is inflated, by two criss-crossed inflatable tubes forming a dome. The tubes ar e criss-crossed at a vertex of the quadra-pod. Lower ends of the four legs are mounted to the fou r corners of the base, one lower end per corner. A flexible net is mounted within the dome so as to drape completely across the interior of the dome and parallel to an entrance to th e structure defined by a front pair of legs and a front edge of the base.
