Skyfire pauses in his attempts to dislodge his horns from the sign and sighs.

"I seem to have crashed into something..." He hasn't figured out just what he's gotten his horns tangled in, or where he is "...and I think I'm stuck..." but he knows it's not where he was not long ago.

Skyfire is clearly fighting with the sign, and he's not winning. There might be a few holes in the back of the sign later... or pieces of his horns if it comes to cutting them off to get himself free. Though he stops struggling when he realizes whoever it is that is approaching is fairly close, not wanting to hurt anyone.
