during one of last years bilzzards, a few friends of mine and i took advantage of the town plowing all the snow in the whole town to one location, interstate shopping plaza right off rte 17. there were numerous mounds at least 20ft high each. we build the craziest snow igloo ever right in front of borders. the mound was a little over 30ft high and we dug out the indsides. it had 2 rooms inside on two seperate levels, snow couches, the works. each of the two rooms could hold about 15 people. sadly the town moved the mounds of snow the very next day.
i know somebody took some pics of the inside of one of the rooms, i'll see if i can find em....
