Thanks for the tips guys. I know I'm overthinking it. It's just a few firsts for me. First time driving alone long distance in the winter/potential snowy conditions and first time driving this car long distance. You guys say it's not that far but for me it is. I don't travel that much and every other time it's been to Florida by plane to visit my grandparents. This will be the second time I drive down by myself so I'm comfortable with most of it.
I'm visiting my brother. All of his friends he met down there are with family and he has no one else. He asked if I was gonna come down because he has four days off in a row and I feel like I should. He's my only brother and I miss him. GPS has me covered and I didn't lose a signal at all last time. I get anxious around new things, so once I get to the part of the directions where I veer off the interstate and find his town will be the only uncomfortable part. I'd like to do that part in daylight so I can see further. I don't want to say I'm worried but that's the only part I'm thinking about too much.
Like most of you said, it's not that long of a drive so there's not much time for anything to go wrong in the first place. If it was the spring or summer I would just drive and not worry about anything but since it's winter and potential freezing temperatures, I wonder about the car and other cars around me.
