Exactly what I thought too!

again what does prep. "Po" govern ? accusative, dative , locative? thanks

[VladaFu]

locative, at least here in the location sense.

In a temporal sense it can be accusative.

[QlIKbokf]

thank you!!

[Vixg]

Would it work without "po"?

[VladaFu]

no

One can use direct object with: "Procestovala jsem sedm moří."
