Lehigh is gorgeous but is not CMU. That said you will spend day after day there for years so go to where you like.
I’m being cynical here but why not go to a CC. If you want to live at home or are worried about the cost of gas to Pittsburgh…I mean this is a time for you to grow and get involved. If you need to live at home to save money go to a cc for two years.
If you want to grow and experience college without mom and dad as a crutch, make friends, get involved…go to CMU. otherwise every time something is amiss and you’ll run home.
College is not just about class. But it appears you are wanting to make it so. In that sense you should absolutely go to Pittsburgh. If you are worried about gas, buy a Prius. CMU will cause you homesickness but it’s how you grow up. Go there!!
