We have our horses at home. It's a lot of work to clear the pasture, but it would have to be done, horses or no horses. We learned the hard way that the daughter's family and DH and I cannot all go on vacation together. The trusted friend and neighbor let us down big time and did not care for the horses as she promised. We came back to horses in a very sorry state. If we had boarded the horses, they would have been fed while we were gone, but then again, we wouldn't have had the $$ to go because of the high boarding fees around here - Catch 22?
Next year daughter will have to limit her sojurn with us on vacation to just a weekend - since the horses will be in a (by then) all cleaned up pasture with a big spring fed pond, another neighbor up the road will only need to check on them for the couple of days that daughter is gone.
However, if we were boarding, we would have ready access to people with WAY more experience with horses to turn to for advice - hey wait - that's what YOU guys are for!
