The original sentence:
If the water was moving with the wave, the ocean and everything on it would be racing in to the shore with obviously catastrophic results.
I like to confirm that this is a complex sentence in a subjunctive mood for both the dependent and independent clauses, although it is not typical to use a continous tense in subjunctive moods.
How to understand the adverb "in" after "racing"? Is it fine to use "...racing to the shore..." or "...racing into the shore..."?
