High fat being unhealthy is going the way of the telegraph if you've been paying attention to health news. I'm with you on the salads as I'm among the 0.00001% that tastes the bitterness in iceberg lettuce, and that's is about the only healthy option from the onsite vendors (I do eat non-iceberg salads). The Major Goolsby burger is big enough to fill you with no fries and no bun, or get a couple of brats, no fries, and don't eat the buns.
The absolute worst is the week with no ice tea. Why are there are no unsweetened drinks (fake or real sweetener) besides water? I can get by eating some cheese curds and fries in the mix, but I can't even choke down sweetened drinks.
Like others have mentioned, I still indulge some during the week, but walking several miles a day certainly makes up for a lot of that.
