at night, the air sinks (flows downhill) in Chavez Revine. Its hard to hit a hr in the eveing there. during the day, as the heat rises from the LA basin, WHOLE nother story. think of it like Wrigley West Yeah, the patterns are kind of interesting. Just because this is a night game, it won't get dark until 8pm or so. And even then, the marine layer doesn't always settle in at dusk. Sometimes, it creeps in while it's still light out. But on a clear, sunny day, all bets are off on how many runs can score. It's interesting stuff, really.
