by the river near me is a beach. as i walk above the cliff from it next to the rail road tracks i can hear clink clink clink as each wave hits the beach. beer bottle pieces everywhere. i hate polution. so i figured id do something about it! i go down there and load up as many beer bottle bottoms as i can carry in a sack.it gets heavy fast. its not only beer bottle bottoms its all kinds of bottles. i love the old milk of magnisha bottles. anyhow, since flint around here is few and far between, i make glass points. now i heard that glass isnt as strong as stone. i beg to differ. i found some flints chert pieces around here that werent as good as glass. ive used alot that was better though. but all in all its a resource far as im concerned.someone has to get rid of it. and i do, on my arrows. lol sometimes you find porcelain like the white point that is up there.love that stuff but its few and far between.
