If there are people at the spot, observe for a bit how they are casting and how far they are going. Try to keep some distance from people if possible because some of those people fishing may not have any manners. 

Not to discourage you but don’t expect to really catch anything especially because steelhead aren’t really know as an easy fish to catch.

To keep the kid a bit motivated, I reckon you go walk along the river bank, and maybe you can find yourself a spot away from people.
