The third Sunday this month feature A Gathering of Gamers on Sunday, October 18th, set up by the South Lakes Area Gamers here. The event takes place at the Pizza Ranch in Elkhorn, WI, and requires a $12 fee for the all you can eat pizza and fried chicken buffet (salad bar, soft-serve ice cream machine, etc.) plus unlimited soft drinks and coffee from 11 am to 8 pm. There are two Burlington Gamedays schedules for next month, the first on Saturday, October 3rd, and the second on Saturday, September 17th. They are set up through the Burlington UCC Game Day group on Facebook here. It will be held both times in Burlington, WI at the Plymouth UCC space, taking place from approximately 11 am to 5 pm. They sometimes focus a bit on RPGs on the earlier date, since they are mostly a board gaming crowd, but check in to be sure.
Those late month gamedays, however, might lose some attendees to the local Gaming Hoopla held on October 16-18, 2015. It's a Mini Hoopla (no prizes, auctions, or frills) being held at the Johnstown Community Center located at 9937 E County Rd A, Janesville, WI 53546. Hours are Friday: 12 Noon to Midnight, Saturday: 8am - Midnight, and Sunday: 8am - 6pm. Admission is $10 per day or $25 for a weekend pass. More information can be had here.
Also, coming in early November, don't forget about GameHole Con 2015 held on Nov. 6th - 8th, 2015. It's at the Alliant Energy Center Exhibition Hall in Madison, Wisconsin. Registration for events is already underway so find out more here.
