orange slice wedges, half banana ripe not green, small boiled red potato with skin, fig newtons (a must).
some even offered GU (I don't like), shot blocks (I NO LIKE). If really desperate, I'll take gatorade (awful stuff). I'll take some other "advanced sports drink" with god know how to pronounce synthetic ingredients Cytomax citrus flavor was my choice of poison.

I'll pass on cookies, Oreo cookies and even granola bars.

Never had watermelon at rest stops...
