Not only was it the first Clay County seat, but it was also home to the county's first framed dwelling, school, courthouse, post office, saw mill, polling place and newspaper -- to name a few.
Now the Peterson Heritage Bi-Annual Tour, which gives visitors a look into that history, is adding two new firsts: two concerts and a noon meal.
"We're changing it up a bit because times are changing," said Bernie Nord, secretary-treasurer for Peterson Heritage.
The tours begin at 10 a.m. and lunch will be served at the Peterson Legion Hall from 11 a.m. to 12:30 p.m. Lunch will include pulled pork, baked beans, chips, drinks and desserts.
"Jerry Johnson will be cooking with me," Nord said. "He's quite popular for that. He makes a lot of barbecue sauce for Smokin' Jakes and Table 316. That's the sauce that will be used."
Following lunch, visitors can stick around at the Peterson Legion Hall for a concert by the band New Harvest, which hails from northwest of Chicago.
"They do country, rock, classic rock and blues," Nord said. "They're very, very talented."
In advance, the cost for the tours, meal and concert is $9 for those 11 and older, $5 for children ages 6 to 10 and free for younger children. At the door, admission is still free for young children, but the prices go up to $6 and $10 for the other age groups.
Tickets may be purchased in advance at the Thrift Store in Peterson or by calling Carmen and Burdette Stier at 295-6443 or Nord at 295-7400 or 847-401-2376.
For those just wishing to take the tours, ticket prices are free for young children, $2 for children 6 to 10 and $5 for those 11 and older.
The tours will include Clay County's first framed house, the Farm Machinery Museum, the block house from Fort Peterson, the J.A. Kirchner house, Rock Forest School and Jim's History Barn.
Other events include the firemen's feed from 5 to 8 p.m., a car show from 5 to 9 p.m. and a beer garden from 5 p.m. to midnight. A free-will donation will be accepted at the firemen's feed and car show.
Individuals who miss the first New Harvest show, or who just want to see them again, can catch them at 7 p.m. at 108 Nash St. Tips will be collected at that show.
"It's gonna be fun," Nord said. "It's an all-day event where people can get out and see Peterson. The museums are going to be open and manned from 10 a.m. to 5 p.m. so people can go whenever they want to, instead of scheduling a tour. There is a lot of neat, old stuff to see. It really is pretty cool."
