The good is a chance to develop into... whatever that next level goal is (draft, D1, D2, D3 or NAIA). For some, it is a chance to improve grades for that next level. If you're good enough, they will find you.
The bad is that you may end up at a non-residential junior or community college that has no real collegiate atmosphere or typical college activities. In the case of a non-residential school, freshman are living in off campus apartments with no RA, and no campus security. The neighbors will be adults and families and real world situations.
The ugly would be some of the facilities which can range from very nice to much worse than a kid's HS field. In some cases, JUCO's play at a high school facility or have to play at two or more fields. I've even seen one that was a city field located at an elementary school.
