My son attended Bama. We are Californians but he was in TN most of his life. Bama has 1500+ Californians. Not sure about Auburn but I don’t see friendliness or assimilation an issue. There are less than 400 undergrads from CA. I’m not a Southerner (although I’ve lived in Tn for 20 years) and I’m in Alabama regularly for work, and I don’t find racism, anti semitism, or jerks in general. Just nice people - occasionally ignorant but nice
Auburn is a cut above demographically.
In theory Auburn students from afar will fly to Atlanta but could also fly to Columbus GA or Montgomery AL which are both closer.
Auburn is more regional than a Bama, likely based on the lesser merit. But still has many OOS kids (just not as many and not as widespread), but most are in state and from Georgia (Atlanta where it’s really popular for the kids that don’t get into UGA or can but want to go away - I know a few).
Groome is one shuttle that runs daily service between Atlanta’s airport and Montgomery with an Auburn stop (that doesn’t mean the university) . Where they pick up and how you get there I don’t know. I would ask admissions - they will have transport to the airport info as I’m sure they are asked by folks like you regularly. Some schools charter buses at holiday time. I don’t see anything on their website though.
I also imagine there’s a ride board and you can find a returning or departing student for a lift for a fee. Or their friends, once they make them. The airport is on the way to the most affluent parts of Atlanta, where many will come from. Convenient - Auburn isn’t in this regard - air transport.
I don’t know what mid October means. You can call and ask admissions but it will be here soon enough.
Auburns campus is way smaller than UGA, which for many includes a bus it’s so large. The town is nicer than Athens but that’s subjective - Athens is bigger and some love it as a favored college town
As for Baylor, it’s religious and there is little in Waco. It’s a nice campus but not in downtown (not far) which is a good thing. Not a nice city. They’ll say you don’t need to be religious but I’ve worked at two companies with a huge Dallas presence - and all I know who have gone are very religious. As the top niche student comment says, it’s God’s school. TCU will be very different.
I’ve only driven near but haven’t seen TCU. I’m sure it’s very nice with lots and lots of wealth. The top 3 comments all say wealthy - with the top being wealthy intelligent party animals.
What major ? Is your student religious ?
How did they pick these four ? Just curious.
Hope that helps.
Good luck.
