There's a "rode hard and put away wet" joke just dieing to be told.
LOL....If you ride 'em hard and bring them in wet, you've got to give them a good cool down and sponge them off, otherwise you are at risk for having your mount come up sore the next day.
How did your comment relate to the 'Always Hungry' topic, MacGyver?
I suppose it could relate to burning more calories than the diet is providing.
