Jersey Giveaway

Howdy, I just wanted to ask a quick question. I'll be going to tomorrow's game and want to try and snag the Altuve jersey from the giveaway. I managed to get an Orbit bobblehead last week when getting to the gates as they opened, but I'm guessing I'll need to get to Minute Maid earlier for this one. For those who have gone early for other giveaways, would an hour be long enough, or would I need to get there earlier than that? Thanks 🙂
