My son rents his books! I have the pleasure on mailing them back, so much cheaper! This is his last semester at Geneseo, with hopes on grad school. He is the first of my five kids to go to college. I am very thankful he has set a great example for the other 4, all younger then him.
congrats on your son's accomplishment and example. I think if one wants to go there are many creative ways to do it. There's more than one way to skin a cat.
One thing I like about BYC is that you can get lots of ideas and choose the ones that will work for you.
