We have been to County Line Orchard as well but for us it was way more than 45 minutes away, so you may want to Yahoo or Google it. MapQuest gives you the wrong directions. It was great, it has a huge store and a lot of activities. It was pretty crowded when we went and we had to stand it quite a long line to pay for our apples. This was a couple of years ago though, so it may be different now.
This year we went to Woodstock, IL. We started out at Homestead Orchard. We checked their website beforehand, as they suggested and it said that there was a lot of available fruit (we wanted to go there because they also have pears and raspberries) but when we got there the woman told my husband that all they had was golden delicious and that we could "take our chances" on the raspberries. We wanted pie apples, so not golden delicious and when he asked about other locations nearby she didn't want to share any information. So I would not recommend Homestead. We ended up at All Season, also in Woodstock and they had plenty of apples including honeycrisp which I guess is hard to find and people really like. We were very successful in our picking and had a great time. No hay ride or corn maze, just apples and pumpkins. It was a little crazy in the store, it is not set up in the most efficient manner, but the orchard is very close and easy to navigate and it wasn't too crowded once we got out of the store. We will definitely go back to All Season.
This website is easy to navigate around and has some great information:
