Human error being what it is, I prefer to have a second brain working on the situation. Plenty of bike accidents happen due to rider error - so do plenty of equestrian accidents. I think ottbmare upthread said something like 75% . . . I think rider error might be a contributing factor in even more.

A good horse will spot and avoid holes as well as ant beds, low boggy places, and so forth. They're subject to all sorts of ailments (never had one get an infection from a stone bruise though) but they never throw a rod and they don't run out of . . . grass.

That's the difference between a living creature with a brain and a lump of iron.

I just prefer the predictability of the bike. Not disparaging horses (being here in TX, we do have a fair number of them around). As to low, boggy places - those are the most fun!
