Turkey legs: The good, the bad and the grisly
The good: First of all, they're portable; you can gnaw on one and still have a free hand to push a stroller, hold hands with your spouse/partner, or walk your dog (although the dog might be a little distracted). They are high-protein, low-carb, making them a better choice for street food than, say, a funnel cake. They're big enough to share. They provide good photo ops. And if needed, they might make a decent weapon.
The bad: Street-food turkey legs can be more than twice as large as store-bought turkey legs, and the high protein content also comes with a high calorie and fat-gram count (more than 1,400 calories and 60 grams of fat per leg). Yes, they're big enough to share, but the 2-pound portion size is still a lot of food, even for two people. And they can be very messy. You may need that other hand to hold a napkin. Or a roll of paper towels.
The grisly: Make that the gristly: The turkey-leg meat is often accompanied by a lot of inedible, unchewable ligament that tends to get in the way of your enjoyment. Artists at street-art fairs have complained that turkey-leg eaters can leave greasy fingerprint stains on their art. Vegan blogs point out that farm-raised turkeys are often not treated humanely, and that some are so fattened for their breast meat that their legs can't support their weight.
