CORRECT!

MOAs (Military Operating Area) are defined by the AIM as '...airspace of defined vertical and lateral limits established for the purpose of separating certain military training activities from IFR traffic.' Pilots operating under VFR in MOAs should exercise extreme caution during time of military activity. The nearest FSS should be able to inform the pilot of real-time operating hours of MOAs. MOAs are depicted on sectional, terminal area and low enroute IFR charts.

The county airport that I trained at for all of my ratings, up to CFII, was located directly under the centerline of a military training route, airspace similar to that designated as an MOA. Fast-moving fighter jets would routinely come screaming over the center of the runway at treetop level and disappear from sight to the east. Common wisdom had it that, 'Oh, don't worry about those guys: they have you on TCAS'. WRONG!! I recently spoke to a former F-18 jockey who told me that those guys are heavily involved in their training mission and aren't necessarily looking out for us slow-moving 172s. Sobering thought...
