When I got her as a companion she said she wanted to pay respects to her ruined caravan. Where is it? It doesn't show up as a quest and therefore no map marker.

I think its west-ish of the NCR camp thats near Vegas, it's called Cassidy's wreacked caravan or something like that, there a dead pack bramhin and an ash pile or two there.

It's on the road to the East of Camp McCarren
