Field Drinkers

This is not so much a review as a brief comment on the type of field drinker that I prefer.

This make of horse drinker uses standard parts which are readily available.  I find all plumbing needs maintenance, these are just easier:

They can be purchased online from:

In the field, the horses prefer the larger sizes where they can both easily drink at the same time.
