JG, Good work! Keep it up!! hey JG, believe it or not i was aware of your writings (in a positive way). i read your previous writing and i was stunned by the way you write, the person who is pursuing mechanical engr?? so, i this time, i didn't have the courage to read your article directly from the sajha. i copy/paste in the MS word and tried to get the meaning of those words that i didn't understand. sounds pretty funny huh..!! or does it sound that i am bold enough and hard-working enough to read your article in such a complicated way?? hahahaha....!!!! anyways, i was there in carbondale for 4 years. i went southern illinois universiyt. it's a nice place though, you should also begin driving during the day and see around the southen illinois areas ( uncountable lakes in these areas).
