Blizzard of '78 - I was 4, but I have vivid memories of snowbanks taller than me and sliding down all the snow that had blown between our cars and my dad being home from work all week because nothing was moving.
6/1/2011 - Working in Marlborough, MA at the time watching the cell develop and seeing the board light up when the first reports started coming about the tornado in just as I was leaving for the day. Darkest western sky I can remember seeing from any daytime storm so far away.
Hurricane Gloria - I think I watched Dick Albert and The Weather Channel non-stop as a young 11 year-old the days leading up to the storm. We had a huge yard with no overhanging trees, so I spent a lot of the storm outside in the wind once we lost power as we were on the dry side of the storm.
Jan-Feb 2015 - I am putting this stretch of weather in as I was living in the Cleveland Circle area at this time with our 7 month-old daughter. Watching the snowbanks get higher, and higher, and higher was amazing. Just nowhere to put the snow by the end. That combined with trying to push a BoB jogging stroller around after parking who knows how far from our apartment because of all the semi-abandoned cars buried by the snowbanks.
Ice storm 2008 - Living in Maynard right on the Assabet River at the time just on the edge of the accretion. The hillside above where we lived was covered in ice and bending trees, but down where we were, it was OK. Drove to the office in Marlborough to find branches down everywhere and no power. Had no idea until I got home later how close we were to not having power for a week.
Honorable mentions: 8/5/2015 hail storm and a fun drive down Beacon St in Brookline coming back from daycare with daughter in the car. 12/14/2007 snow gridlock.
I was in school at LSC during the Perfect Storm and April Fools, so I didn't experience them directly, only from afar. Bob doesn't really make my list as for where we lived, it was a rainy, (really) windy day and we didn't even loose power.
