^^^^^ Exactly.
I have the bike, hands firmly on the bars, both feet on the ground, and I tell her I'm ready. She uses my left shoulder to help pull herself up to get to a standing position on the left peg. The right foot just steps across the seat, does not have to be swung around the back, finds the right peg, and she settles down.
Basically: climb up, step over, sit down.
For some reason my wife dismounts to the right. Don't know why.
I actually had to learn to do that myself when I loaded the pillion seat for a camping trip last April, I had to stand on the peg with the bike on the sidestand and step through the tiny gap between my tent and sleeping bag behind and my tank bag in front.
Oh, yeah. Sooner or later somebody's gonna punch you about your sig pics. There's a size limit, basically so the thread page fills up with useful information to peruse rather than repeated viewings of bandwidth-robbing images, which especially annoy dial-up folks, of which there are still 2 or 3. (Not me, just sayin' there are.) Guidelines
