Has anyone used the BJC select on buses? I like that it feels solid and chunky but worry that it will be a monster to get on a bus. I know that it folds down in two rather than one piece so really I would be aiming to be able to get on the bus and keep it up ( where there was space for us) as putting it down in two pieces plus holding onto a baby will be impossible. I will mostly be driving places, but don't want to completely rule out getting a bus every week or so.
