Thoughts on solo camping, pros/cons

Since I was a kid I've always camped with my family. Every summer we would usually end up in Maine. This year my family can't go and I have a 4 day weekend coming up and found an available site for those days. I would love to go, but I also am slightly reluctant to go alone.

I'm not exactly what sure is freaking me out, I know the area of Maine pretty well, so it's not the location or anything. Maybe it's not having anyone along side, but at the same time I feel like doing a thing like this might be even better than doing it with a group of people.

If you have any insight/opinions on camping alone, please share!
