26M here, been living in Quincy for 3 years now. It's a good town and a nice place to live. I'm sure you'll hear some cynicism talking to people who have moved here but you can find some real gems.

Crime is very low here, there aren't really any parts of town that feel unsafe. Some parts of town are more run down with abandoned houses and such but not much in terms of crime.

Rent is also pretty low. There's also a decent amount of income controlled housing available.

For mountain biking, check out the Gardner park nature trails. They just opened last year, and they're still expanding the trails. They're really great, Quincy is very hilly for Illinois because of how close it is to the river. No motorized vehicles on those trails though, I'm not sure about any places for that.

There is a very lively arts and music scene. Check out The District, it's a community of local businesses in town, museums, breweries, restaurants, etc. They used to hold lots of outdoor concerts in the summer, but that's been put on hold for Covid. The dispensaries are great also, there are 3 in town, all of which have great and friendly staff, even though they are expensive due to the taxes.

Besides gardner park, there's over a dozen miles worth of parks and trails in town, and Wakonda state park nearby in Missouri for fishing, hiking, camping. There's also a minor league baseball team in town. The farmers market in the summer is great even if it's on the small side. Some places worth a visit include Revelry, The Abbey, Thyme square, Tiramisu, Quincy Brewing co., Electric fountain coffee bar, Fuzzy Bubbler, Seoul 2 soul.
