Editing 1998 NPPL Chicago Open (section)

== Playing fields and weather ==

The tournament used woodland, Hyperball and a field combining inflatable and fabric bunkers. WARPIG described the woodland layouts as wider than those familiar to some visiting teams, requiring adjustments to their usual tactics.[1]

Delivery problems delayed the planned inflatable field. During five-man competition, the layout instead combined USPL inflatable bunkers with fabric-and-aluminium obstacles associated with the Challenge Cup, producing a field containing 38 obstacles.[1]

Players faced heat and humidity. Thunderstorms before play on Friday brought down some netting and portable bunkers, which were restored before games began. Further storms on Saturday night were followed by cooler conditions for the ten-man semi-finals and finals.[1]
