Please log in for more thread options Point well taken.
I have lived in south Florida for the past 25 years (moving soon) and
have personal experience with hurricanes, building on swap land, and
ground water 10' below the land/fill's surface. Must have been a
pretty challenging job. ("fun with pillions")
I'm not an mechanical engineer, but if it doesn't make sense in a
spreadsheet it probably won't function well, and if it does it's dumb
luck. (I'm not very lucky)
Thanks.
