Millville (KMIV)

I might be flying to Millvile (KMIV) in the near future. I have never
landed at a field with an FSS before and I have never really
understood the process. With the changes that have taken place over
the past several years, I'm even more confused and would appreciate
some guidance.

I don't believe that there is an FSS on the field any longer, but
there apparently is still an FSS. I have seen references to an FSS
frequency for Millville (122.2). I have also seen the CTAF (123.65)
refered to as an FSS tie-in. I don't know what that implies.

Bottom line is that I don't know who to contact and how to refer to
them. Should I be calling the CTAF and refering to them as Millville
Radio or call the CTAF and treat it as any other CTAF and simply self
announce? Or should I be calling the FSS frequency and then who would
I get? Any help in keeping me (and others) safe and helping me avoid
embarrassent will be appreciated.
