Personally, I wouldn't voluntarily go two weeks or more without seeing my family. I spend a decent amount of time with my family every day, and to me that is bigger than law school. But priorities vary by person, I suppose.
Studying on a bus is somewhat productive, but it's not ideal.
"Obviously it's not undergrad" is a cute thing to say in acknowledgment, but you're probably brushing off the difference too readily.
I'm sure Opie is the only one that can judge how often he wants/needs to see his family.
Studying on a bus is fine, especially the Megabus. It's not hard to read on a bus, and it has wifi. And, honestly, how much are you realistically studying a week? There's not reason people can't front load studying in the week so that they can take the weekend off if there isn't a memo/brief due and it isn't the last 4-6 weeks before finals.
If Drake makes more financial and family sense, then definitely go there. But don't let the time commitment of law school scare you off - It doesn't consume your life. I know people that commute an hour a day to school, people that go to DSM every weekend on the Megabus, and people that drink from FAC til 2am Sunday then get up at noon and maybe do some stuff Sunday afternoon. I also know people that study/work on LAWR stuff until 10 or 11pm every night, get up at 7am to head to school to read before class, and study a decent amount on the weekend. It depends on how efficient you are, how quickly you can read while understanding what you read, and how easily distracted you are.
TL;DR - Everyone's situation is different, and only you can really analyze yours. Don't let one opinion on EITHER side of the spectrum decide for you.
