Thanks all for the responses. I've now run into people who hate short sleeve t-shirts. For me, if it's cold enough to need something on my arms, it's time for a jacket or sweatshirt (over my short sleeved t-shirt

).
Any reason they couldn't offer a choice? I know that some shirts like the marathon shirt with the park logos would need to be long sleeved either way, but the others? I know they get a price break for ordering in bulk, but I can't seriously believe that the price break for 25k of one kinds is that much (if any) better then 12k of one and 13k of another. Offering a choice would seem to be the best of both worlds with very little (if any downside).
