Sorry for the late report, Jim - we combined with a camping trip from which it took a bit of time to recover. At any rate, this event is a fun, homespun, family event - the food is quite good, the entertainment is enjoyable and the beer is cold. We were one of the few families who prepaid online: we still had to stand in line to get our tickets, but it was good to know we were assured to get in.
The event mostly happens behind the church; you don't see much of it when you get there:

but in back, there's a large tent with a "beer garden" (which was cool and breezy despite the hot day) and all kinds of carnival games for the kiddies: Sparky apparently nailed the dunk tank and the milk bottles and came home with an armful of prizes.

Unfortunately, we arrived a bit on the early side (about 1:15) so the lines were long and it was hot...and I forgot to take pictures of the food! The meal that you pay for includes choice of standard roll or rye bread and butter, a nice chopped vegetable salad (cucumber, tomato, onion) or sliced tomatoes, applesauce, hot sauerkraut with bits of bacon or ham in it, truly beautiful sweet corn with a butter dunk, and pork. Drinks are priced separately - if you go next year, save yourself time and get an extra $10 of tickets which are $1 each, beers and alcohol can run you 6-8 tickets, carnival games and sodas 2-3 tickets (we did get $6 worth of tickets to defray the processing fee, which bought us 2 bottles of water) Plates were filled to groaning.

It's good to know Cathy2, though - at her direction above, I scored this lovely plate of crackling skin, some of which was a bit underdone, but much of which was delicious and fatty and crunchy and had some of the best pork still attached. This came from a gigantic garbage bag, where 6-7 hogs worth of skin had been deposited for disposal.
A few minutes after we'd finished eating, I wandered back to the kitchen and discovered Cathy2, Cathy1 and Helen headed for the screen kitchen for their own plates of crackling skin. Cathy, clearly a veteran, had ordered her meal in a clamshell takeout box that held much more - she also had figured out how to get the choicest pork (ours was mostly "white meat," and was honestly a bit dried out) by ordering meat with bones and "crispy bits." We had a lovely conversation while Sparky knocked things down with his pitching arm, and then packed up and headed home. Always more fun with another of our own, right?
We left via the forest of smokers, so Sparky could see what it looks like to cook a whole pig (they were barely recognizeable, sorry, again no pics) At any rate, we'll probably be back next year - although it was not that far of a drive, it really seemed like we'd left the suburbs and were deep into farmland. The church is very charmingly surrounded by cornfields, and we were able to stop at the Kishawaukee River that morning to fish (more on that later.)
