I guess I'm not clear on how a hydrant works and what it offers over the hose bib.
Anyway I went ahead and just used PVC as originally planned. I will probably do something along the lines of what vsheetz has done for supporting the pipe. I will either encase the last run of the pipe and elbow as well as the supports in either concrete or some sand mixed with portland cement (and then wet for hardening).
btw I was in Escondido today at the Harborfreight to buy one of their rotary hammer SDS drills.
Sounds like the way to go don't want to complicate a simple spigot issue.
It's not like you are piping a house or in a freezing area.
Certain area's of the States require much more thought and work to install a spigot outside.
