you "need" to carry bonds with you?
eh.. yes and no. if you go a long way.. you get your taxes in bonds anyway... so you don't need to start with anything.
and you need bonds to trade inside your own realm anyway.. location makes no difference. the foreign bonds thing.. is just a game balance thingy... bonds don't get robbed and so it's fairly risk free to hump a load of bonds to another realm, as opposed to a load of gold. (yes.. trade is fairly risk free too... but they are sticking in delay or some such later)
eh.. as for the 1k vs 100 bushels thing. technically, a trader can match up the 1k and 100 bushels (eh.. if there are 10x100 and 1x1k)...
