I checked "ready mount" but I also do the "seat mount", just sort of depends.
I've seen quite a few old pictures where people were riding frames that are huge for them by modern day standards. In some cases, it's kids riding what are either adult or bigger-kid bikes, in other cases adults riding them. I think that is the only reason to do the "side mount", because I'll bet some of those guys couldn't stop and straddle the top bar. And that was all probably a carry-over from the high-wheeler days, for that matter.
