I have a couple. I LOVE the frozen strawberry lemonade at McDonald's that's only available in summer. I try to limit myself to 2 or 3 over the summer.
I also love fried dough at summer carnivals. I haven't had one in several years so I think this may be the year to indulge. And I know, it's carbs fried in oil, but the best way to eat it is spread with BUTTER and then sprinkled with cinnamon sugar. Yes fried food spread with butter. It's why I have it only once every 10 years!
