thanks for the info. I will consider the IGH idea.
I have visited twice the US (LA and NY) and comparing the city roads to my home town(Jerusalem, Israel)
it is hard to explain the challenges a rider go throw when riding between angry drivers, holes in the very narrow roads (and up hill half the time)
I think, from experiance the most challenging point will be the stopping and starting with the load(1-2 kids =130lb ?),
and going on and off sidewalks (which is necessary) will be almost impossible.
are there any haul-a-day riders who can share their experience?
