Just an aged fwiw.
Back when I was using one, I'd have had no hesitation seconding the trailgator option. Used one for years .... the trick is to train the wee one to pedal when necessary; I loved feeling that wee kick as she "did her bit" to help Dad up a hill
. Aye, but that was 15 years ago, back in days when it was pretty normal to expect,
AND GET, that little bit of extra courtesy and space you would hope for when you have a child in tow. There's still bits of Leeds where I'd have no hesitation - but that courtesy and space just ain't a given any more.
BUT ... there are parts of town and some roads where, now, I just wouldn't dare. It's not the "nose-to-tail" sections that would bother me - it's when the "nose-to-tail" breaks up, and the b*****s think they can see "open road" and "freedom". Or the fast rat-runs - no, no, no!
