Just moved the bulk of my record collection from a 10x10 storage unit to a 10x15 unit. Though the move was only 3 doors down, it took 3 days (about 24 hours) to move. You can see pics here: http://PDX78s.cdbpdx.con/Stor/ Don't know the physics of this, but the 10x15 unit is full to the ceiling with the stuff that came from the 10x10 unit, CDB
