Jarren Williams will be a Cane. Small concern, legit or not, from family just about environment to get in trouble off campus.
Very simple to address, particularly with an on-campus visit.
Coral Gables is the first planned community in the US. All of the streets were laid out in the 1920s, and the University was planned all along (though construction money did not come in until later).
The campus is surrounded on 3 sides by residential Coral Gables, and on the 4th side by Ponce de Leon/MetroRail/US 1, with some commercial development along US 1, then more residential.
What that means is that you have to drive several miles to get into any "bad areas" so-to-speak. The immediate surrounding area, and a radius of several miles, is largely high-dollar residential and commercial. There's not really a "club and bar district" for miles. Yes, there are a few spots where you could go to acquire alcohol, but not very risky/rough for several-mile radius around campus.
That does not mean that a kid can never find some trouble. Sure, but it requires a bit of effort, it's not like a college campus where people may live within a few blocks of the bars or a few blocks of a rough part of town.
I'm trying to use some polite language, but living on campus at UM is (for both good and bad) like living in a bubble in a lot of ways. It is possible to go throughout most of your days and weeks without having to leave campus for much, or without having to drive for much. Security is greatly improved from when I went to school in the 1980s and 1990s.
Should be able to address all of the family's concerns.
