sideways bales anyone?

[Carlos A Soto <mejicano@prodigy.net.mx>]

    Hello to all of you. My partner and myself are thinking of building this
year, and we were thinking of using the bales sideawys on this new project;
instead of laying them flat, putting them on one side. Well, since we don't
have much experience, we really don't know what the pros and cons are,
compared to the more common way of stacking them up.
    These walls would be for a post and beam structure, in a very flat lot,
plenty of space, hot and mostly dry weather, little rain, and "wheat fields
as far as you can see" (ok, that's from a Garth Brooks' song).
    All I know is that it would take less bales and the walls wouldn't be as
thick. What else should we be considering before we start?. We really would
like to hear all the pros and cons, especially from people who had done it,
seen it, or studied it.
    Thanks for all the help, off list replies are also welcome.
