I grew up in Parsons and I think - if you like small town life - you will like it there.
As everyone else has mentioned, it started out as a railroad town, then got the Ammunition Plant during WWII. The "plant" is finally closing, and I'm not sure about any future plans for it. At one time, there were appx 20,000 people living in Parsons. I would think a better estimate for today would be 10,000. There was a lot of coal mining between Parsons and Pittsburg, leaving "strip-pits" that are good fishing holes, and you can google "Big Brutus" and see the world's largest coal shovel that was in operation there. (or see it in person near West Mineral)
If you go to realestate.com or other realestate company sites, you can find what is available in Parsons. You can get a lot of house for your money! There are many old, beautiful Victorian homes in the 4the ward or the SE part of town. Many have fallen into disrepair of late, as the economy in Parsons is slowing down/dwindling. She was known as the "Queen City" many years ago. The local residents have do a lot to get Main Street reopened and have done and excellent job! Urban Renewal had closed it down 40 yrs ago, and that's what started the decline, IMHO. But businesses had started moving back in and things were looking up until the ecomony tanked.
They have 2 golf courses and a Botanical Garden. There are a group of women who "keep things beautiful" in the summer by planting flowers and trees. And, there is a great turnout for Katy Days! (the MKT railroad or Katy, was what made Parsons) If you go to Parsonssun.com, you can read more about Parsons and all that is happening there.
The people there are very friendly and your kids will have a "Happy Days" existence for the most part. Of course, drugs are bad everywhere and especially Meth in farming states. I would think the drug problem would be worse in Pittsburg, however, as it always has been. Frontenac - immediately north of Pittsburg - is known as "Little Italy". (I will let your own imagination fill in the blanks)
The medical center, Labette Health, is good for a 100 bed hospital. (appx 100 beds). They have a new administrator there and he has a lot of good things going on at the hospital. However, if you need a tertiary care facility, you will need to go to Joplin, Tulsa, KC, or Wichita. All are about 2 hrs away, except for Joplin which is closer to being 1 hr away.
As far as the schools go, I have no idea any more. Garfield used to be a good grade school, but I don't know about it anymore. Parsons High School wasn't a bad school, there are a lot of us who managed to graduate from there and make a good living! Altamont or Labette County Community HS is more of a technical/trade school (or used to be)
I forgot to add that there are 2 lakes near Parsons, well, make that 3. Lake Parsons, Big Hill, and Grand Lake is about 1 1/2 hr away in Grove, OK. If you go to the thread asking about Chanute (30 miles from Parsons), someone has posted pictures of Big Hill
If you have never been to KS, I hope you make the trip! The Flint Hills are really beautiful in the spring and summer....
Good luck on your relocation!
