We just had 2 HUGE explosions not far from my house!! --a large greenhouse/nursery bussiness is ON FIRE about a mile away!! --its a 4 alarm fire!--and all available units from surrounding towns are on the scene.. They said on the scanner that 2 300 gallon propane tanks have exploded already,and they just now got water pressure to the hoses!.(its been burning a half hour already!)--.the place heats the greenhouses with propane,and also uses waste oil furnaces...I brought my drain oil there before! My house shook like an earthquake,and I'm a mile away!!..I can only imagine how the houses about 100 ft away felt! ..looks like I'll be glued to the scanner again...2 weeks ago it was the dam 5 miles away--now the neighborhood might burn down! Ahhh--they just said they don't think the rest of the tanks are in danger of exploding!!...hope they are right!
