May I get past the entrance gate with jello and watermelon in my bag?

How would you kept the jello and watermelon cold enough

I was able to get a sealed ice tea container and two empty squirt bottles in on the hottest day of the year, but i doubt you'll get those items in, especially if they're not sealed.

In Orange County? Ha, I seriously doubt it!

No

Don't see why not unless there's a big time amount of alcohol in them.

Only if you are "lucky"

I don't think so.

Doubtful
