Great work, Vallie. I like your editing, such as the nice "Jump Cut" at the 0:14 mark. Nice and smooth. I enjoyed watching this. I also get poor audio at that whistle-sign (your opening scene). I've finally learned that I get better audio of the whistle when it's sounding from a further away spot from me, such as if I'm at the Schoolhouse and the locomotive is at the Ranger Station building.
The first cut probably wouldn't have been there, just for the sake of those that would like to see the whole thing, but me and my dad were talking in the portion that was cut out, so I didn't want to include that :p As for the whistle audio, I'll have to experiment with that and see what works best for me. I was thinking for now I might be able to record the audio from my phone instead, because its microphone can handle extreme volumes pretty well, and I always have it on me so it could be convenient... I dunno yet. We'll see!
