It is not a dumb question since many hunters don't realize it is illegal to use a motorized vehicle to locate game. A few years ago I read about hunters who were cited for using vehicles to follow snow geese and then setting up where they landed. i'll try to find the specific section of the regs on the PGC website if is functioning the way it should.
Here is the section of the code that addresses this issue.
Sec. 2308. Unlawful devices and methods.
(a) General rule. - Except as otherwise provided in this title, it is unlawful for any person to hunt or aid, abet, assist or conspire to hunt any game or wildlife through the use of:

(2) A semiautomatic rifle or pistol.
(3) Reserved.
(4) A semiautomatic shotgun or magazine shotgun for hunting or taking small game, furbearers, turkey or unprotected birds unless the shotgun is plugged to a two-shell capacity in the magazine.
