How would I know? I don't live on a farm, so... Actually, if they weren't legal for sale in PA before, they wouldn't be found in Tractor Supply here either. Apparently the law changed, or they found a way to slip by it somehow. It's worth a call though because after shipping you're looking at almost $20 for a stupid spout. At that price I can just get a No-Spill. There's a Tractor Supply about a half hour from here, so I'll look into it.
