So, a college near a NASCAR track is an okay place to go, maybe you can network with people there at the track to get contacts that can help. Race tracks need money year round and hold a LOT of events for all levels of racing. I would start with a small circuit event and maybe volunteer to help the track or teams, see if you can get your foot in the door helping them out, maybe get into a team as a paid employee and see where that takes you. Good luck!
Todd recommends the following next steps:
Unfortunately, there is no racing school to attend to become a driver in NASCAR. However, if you would like to get a step into the door I would suggest looking into schools such as UNC-Charlotte, UNOH, and NASCAR tech. None of those schools will actually make you the driver of the car but definitely could point you in the right direction if you want to work with a team.
As far as driving goes, I drove racecars for 15 years of my life. Getting to the level of a NASCAR driver takes many, many years of experience, talent, and most of all money. Most rides unfortunately are not based on talent anymore and more based on sponsorship money brought to the team.
