Generally yes, if I have an in-person conversation and they mention a place I'll check it out, I've had better luck if I've had a long conversation and they understand my experience they tend to give better info than after a quick chat...
I had a funny one a couple of years ago, in a new area and had a warden check me just as I set up camp, we talked for a long time and I didn't ask about spots but did ask if locals used a certain tactic in the low ground, he said no, nobody does that because it's too low odds... about 4 days later I wanted to do something different for a day and decided to try it regardless of his advice, I picked what I thought would be the best spot and hiked in way early, sure enough, a single headlamp shows up just after me, turns out it was the same warden hunting for himself.. we both laughed about it and he said I was the first person who had asked about that approach and it got him thinking he should try it...
