What are the best aspects of living in Ontario, California as a young adult?
If you are curious enough to ask this question as a young person then I would say that looking deeper past all of the cookie cutter homes and infill building of the past 20 or so years and realize that you are surrounded by a very uniquely historic area.
Whether you were born there or are a transplant, Ontario is a very good starting point to begin exploring greater southern California.
Being that Ontario abuts eastern low angeles county and is pretty much the western seat of the inland empire it is awesome to know that you are sitting in what could be the dynamic hub of the region.
As a young person, you have the opportunity to soak this in and build your future based on knowing that you are conveniently links to not only the region at large but also the inlet of activity for the area.
I was raised in the area and saw it grow very rapidly throughout my young life.
When I was young in the 80s, the city still had a very 50s and 60s vibe to it, and throughout the late 80s there was a big growth spurt that began with the airport expansion and convention center. Even though these projects seemed to be a bit more withheld than I believed they could be (likely due to strong political competition of being own by LAX and the proximity of Anahiem Convention Center near Disneyland)
At one time, Ontario was considered for a possible high speed rail hub that would link LA, Las Vegas AND Ontario. It would have been cool and i think the city could have been much bigger if they wanted.
Anyways, as a young person I believe that the city is ripe for new vision.
