Quoted from Yelobird:
Did you actually lay that game on its side? Never tried that before. Enjoy PBM.
I brought a Time Machine home in my truck on it side with the head off, I was able to put my roll top across and have it hidden and protected all the way home. Worked like charm, I was happy as hell. Really, these things are left standing on end for years at a time, and I don't hear about any cringing, this is just on its side, no biggie.
