what have you done lately? in the holidays we stayedwith my aunt in toronto again. they have been living in canadafor more than 15 years now. my first visit was 10 years ago and since then i`ve been (being?) in love with the place. have you ever heard about lacrosse? it`s the national sport in canada. i`ve got to know it while i`ve beenthere. the native canadians played it long before the europeans arrived. the indian name for it is `baggataway`, but then the french explorers have seen the game, they`ve called it `la crosse`- after the stick a bishop carries. in 1876, when the canadians have found the nls, they haven`t allowed native canadians to play their own game. that changed of course and indians took part in the modern game for many years. the amaricans decided in the 1880s that they liked the game, too, and they have been playing it in the us since then.
