All three of those schools have sent coaches to visit McGaster at his house, the Gophers sent defensive back coach Jay Sawvel.
"He talked to me and my family about how the school is and that they're serious about academics," McGaster said of Sawvel. "It's a big city, nice people."
This weekend's visit will be McGaster's first trip to Minneapolis. The 5-foot-11, 180-pound cornerback has certain criteria he will be looking for on his visit.
"The first think I will be looking for is to see if they have my major—biology, dentistry," he said. "The second thing, do I feel like I'm comfortable around my surroundings—like the people they're recruiting to see if I feel comfortable around those guys? And if I feel like it's my home."
While two of the schools McGaster is heavily considering are located in the Southeast, he said the location of a school isn't much of a factor.
"Distance isn't a big factor—I'm fine with it," he said. "Sometimes you've just got to make the right decision. You gotta do what you gotta do."
McGaster, who has already taken an official visit to Illinois, is in no rush to make a commitment.
"I'm going to take all my official visits to see how other schools is first," he said. "Probably in January I'm going to let everyone know who I'm going to commit to."
