Well Baylor is a big school. These days, or any days for that matter, I'd prefer not to send my kids, or now grandkids, nieces, nephews, etc, to a big school. Baylor isn't the mega-school that UT and A&M are, but it's still big. Big is fine for grad school, since the individual grad programs are nearly self contained and form a (really) small school within the larger one. Plus by the time they are grad students all the temptations that go with the big school town are not so tempting, and they are mature enough to mostly resist those that are.
My older daughter also looked at Baylor and Trinity, before deciding to stay home and go to Austin College.
So you are in the Sherman area? I have close family in McKinney which made Austin a very attractive choice to me in terms of having relatives nearby if she needed help. You are right that Baylor is a big school, and SWU is even smaller than my daughter's high school. I love the student/professor ratio at Austin, Trinity and SWU. They aren't just a number in the professor's grade book in a huge lecture hall. She knows Baylor is a good school, but she really wanted the away from home experience and the opportunity to meet new people. Baylor is such familiar territory from years of attending extended education seminars, athletic events, cultural events, etc. that it held no allure to her. Georgetown is so close to Austin that she has big city amenities nearby, but lives in a small town atmosphere.
