MORGAN Park has taken on the shape of a truck and gooseneck maze, with polocrosse players and their horses scattering the lawn left, right and centre.
The biggest arrival day was yesterday, with an estimated 110 rigs through the gates.
Warwick Polocrosse member Jeff Ferguson said the men on front gate patrol were flat chat most of the day.
"We opened here at 6am and they're still filing through now (4pm)," Mr Ferguson said.
"There were a few breaks, but it's been pretty busy all day."
Victorians and Queenslanders were the most common campers who arrived yesterday, with New South Welshmen among them.
"The Northern Territory guys came through on Thursday," Mr Ferguson said.
Two played from below the border, Trent Mortimer and Wayne Stevenson arrived yesterday and set up camp among the flurry of action.
The pair will play for the under 21s men's NSW side and said they had played together many times.
"We've played together for the last four nationals but we play against each other most of the time," Mr Mortimer said.
The pair travelled down separately, hailing from opposite sides of the state and brought 17 horses combined.
Today, 67 rigs are expected to enter Morgan Park and another 28 tomorrow.
Head out Monday to check out the action.
