I don't need to shoe mine either...just a time thing. I get up at 5:30am to bring them in so they can feed (hot FL sun in summer/august, barn is 10-15 degrees cooler). I leave the house at 6:30am, drop the wife off at 7:30am, then I'm at work just before 8am. I get off work at 5pm, but she's off at 6pm, so by the time we get home, it's 7 or 7:30pm, depending on traffic.
We have time to fix dinner (I'm putting the horses out while she does this, or vice-versa), and maybe watch one TV show while we are eating, before going to bed to do it all over.
It's why we try to have fun on the weekends, but the weekends are also our only days to actually DO anything around the ranch too.
