Does ANYONE know the name of this MOVIE or at least an ACTOR?

please help me. i'm trying to find a specific comedy (i think) movie, but i don't know the name of it. i guess it was made in the early 90's - mide 80's. it involves kids on a camping trip, they're all boys, except for 1 girl. and the man in charge of the kids is an ex-con or an escapee, & i think the called him "spider". a part in the movie was when the girl uses her bra as a slingshot or when the ex-con/escapee pees of the side of a cliff & the cops looking for him are under the cliff & one thinks its raining. but if anyone know the name of this movie or at least a name of one of the actors please post it! thank you!

I believe it was "Bushwacked" (1995) starring Daniel Stern.

Max is a delivery guy. As he makes a delivery, he finds out that guy who hired him was using him to move around money and that he is dead. He is afraid the police will think he is the killer and runs for his life. He his forced to pose as a scout leader for a bunch of kids hiking through the mountains as he is chased by the police.

Quotes:
Fishman: Sir, would it be ok if we called you Spider?
Max: Why the h - - would you wanna call me that?
Gordy: Because it's your nick name.
Max: Well fine then. Call me Spider!
Fishman: Spider. Spider. Spider!
Max: WHAT?
Fishman: How come your nick name's Spider?
Max: Because I once killed a kid who called me Spider, one time too many!
Fishman: Yeah, but how could he call you Spider one time too many if your nick name wasn't already Spider?
