i had a family friend who heated their home with wood, and bragged
about how much money they saved over oil heat

I then asked how much work does it take?

Oh the wood is free from a summer camp they owned

BUT they had to drive there every weekend for the summer to cut split
and haul the wood out of their mini forest. then haul the wood home
and stack and let dry for a year.

as i pointed out to them oil was cheaper.

if compared to the 3 of them having minimum wage jobs putting the same
number of hours in working at the local store, and adding in the cost
of gasoline to haul the many truckloads of wood home each weekend.

one family member admitted it started out fun but became a never
ending job he hated the constamt push to be ready for heat, concerned
all summer long...........

free heat wasnt free at all
