VPB actually has three pump tracks. One tot track (two if you count the little paved one by the playground), one small one by the XS and S jumps and then another longer one up top by the Penitentiary. And yep, I've taken my kid on a Strider bike on all of those. For all but the tot one, I make sure to pull him out if someone is actually using it as intended, but honestly I've only seen like 2-3 adults in all my time there on the bottom pump track (caveat that I tend to go midweek during the work day so I'm sure that factors in). The lower pump track is pretty small so I think thats why it tends to be more kids, as I mentioned I rarely see adults in there because the turns are pretty tight. I did see one guy shredding it up the other day, I took U to the jumps to let the dude have the whole thing to himself. The upper pump track seems to be used more by adults, its a lot longer than the lower one and I think most parents don't take their kids up there because you have to go up the big hill to get to it, but that one is also a little more complicated and people tend to wait to drop into it and form a queue. We only use that one if no adults are up there using it.
For the most part, most other parents I have met at the bike park are either bikers themselves or at least are aware of how dangerous a place it can be, and very mindful of keeping their kids from putting others and themselves in danger. I know that I may seem overly hands on at the bike park, but I always make sure that my son is going in the correct direction of the pump track, waiting for slower riders or at least passing them with a safe margin and giving other people lots of space. It can be hard because he's only three, but he will do the pump track 9/10 in the correct direction but as soon as another kid messes up the order of the turns its like he forgets the correct way and then ends up wandering across the track and I have to pull him out.
