"North Texas was pretty cool," he said. "It's a little small for me but it's a great school."
The large turnout at Kansas State impressed Mayes.
"Kansas State was really cool," he said. "20,000 people for the spring game was a sight to see. It was incredible."
Along with making visits, Mayes has had a number of coaches stop by his school to watch him perform this spring.
"Texas Tech and Rice stopped by last week." He said. "And this week, West Virginia, Ole Miss, Oklahoma, Colorado, Connecticut, Minnesota, and Wake Forest."
Some of these schools are starting to express more interest.
"Ole Miss said they were impressed with my film, they said they watched my film and they really liked it," he said. "OU said I was still on their board for now. They said I'm showing some improvement so that's good. West Virginia said they're interested."
One of the most recent visits came yesterday from Minnesota offensive coordinator Matt Limegrover. Mayes enjoyed his time with the Gopher coach.
"It was really awesome," he said. "We can't legally have spring ball but we did some football drills without pads on and we did some conditioning and he was impressed with that. He told me and talked to me and just that I'm the number one guy on the board right now."
Being the top offensive line prospect for the Gophers is a big honor for Mayes.
"It's an incredible feeling," he said. "I'm really honored to have a program with all the history and tradition that Minnesota has and all the opportunities there, to be number one on their board for offensive linemen for the class of 2013 is an honor."
Mayes' relationship with the Minnesota staff has continued to grow since his visit to Minneapolis.
"I probably talk to the Minnesota staff the most out of all the people I call," he said. "I really got to know my recruiting coach, Coach Poore, and Coach Limegrover pretty good. I mean Coach Limegrover, he knows the game. He's a really smart guy and I like his coaching style. And Coach Poore, I talk to Coach Poore a lot and he just tells me about all the stuff that's good about Minnesota. How it's just like Texas, you can go fishing and hunting like 25 minutes outside the city."
This continuing relationship and recent visit have left the Gophers near the top of Mayes' list of favorite schools.
"Minnesota's still the top but I'd have to say K-State is pretty close behind them but Minnesota's still the top," he said.
As interest continues to grow, Mayes is uncertain when he will make his college decision.
"I really don't know to be honest," he said. "I'm going to try and take one more trip at least, or a couple more trips. I know I'm going to go to Colorado soon and maybe somewhere over the summer. Minnesota's still number one but I just want to do a little bit more looking. This only happens once in your lifetime so I might as well make the most of it."
