Today I took Mac for a trail ride and when we got home I put him in his pasture. The gate was open between Paddy's pasture and PFP's pasture so that they could be together when I left with Mac. PFP's pasture is next to Mac's pasture. I'll spare you the details, except to say that my system for moving them around is complex enough that they never share a fence line.
PFP was happy to see Mac when he came back and trotted into her pasture from Paddy's pasture. Mac had a good roll, then they met over the fence. Paddy had to get into the mix a little bit also, but it was fairly uneventful.
