MEMORANDUM *

Gene Willison appeals his conviction for camping on public lands longer than fourteen days in violation of 43 C.F.R. § 8365.1-2 (a), and 51 Fed.Reg. 10277. Willison raises three claims of error. We have jurisdiction pursuant to 28 U.S.C. § 1291 . We find no merit in Willison’s arguments and therefore AFFIRM the judgment of the district court.

DISCUSSION

Because the parties are familiar with the facts of the case, we will not repeat them here except as necessary to explain our decision.

*618 A. The Regulations Are Not Void For Vagueness

We review de novo a claim that a statute or regulation is void for vagueness. See United States v. Erickson, 75 F.3d 470, 475 (9th Cir.1996). Willison was found guilty of violating a regulation providing that “[o]n all public lands, no person shall camp longer than the period of time permitted by the authorized officer.” 43 C.F.R. § 8365.1-2 (a). In the area in which Willison lived, the time limit on camping is fourteen days:

51 Fed.Reg. 10277.

This regulation is not vague. It is clear enough to enable people “of common intelligence” to discern its meaning. Hynes v. Mayor and Council of Borough of Oradell, 425 U.S. 610, 620 , 96 S.Ct. 1755 , 48 L.Ed.2d 243 (1976). Willison’s arguments as to why the statute is void for vagueness as applied to him-that he was mining, and not camping, and that his occupancy of the site was too permanent to constitute camping-are without merit.

B. Jury Instructions

We review a trial court’s determination that a defendant is not entitled to a particular jury instruction de novo. See United States v. Hopper, 177 F.3d 824, 831 (9th Cir.1999). Willison’s argument that he had a right to remain on BLM land pending the outcome of litigation over the terminated lease is insupportable from a legal standpoint. There was therefore no error in rejecting his proffered instructions. Willison was not mining, and had not been mining since 1992 when he was first enjoined from doing so by a federal court. If he was not actually mining, he had no right to occupy public lands for more than fourteen days. Federal regulations make clear that squatting on public land in anticipation of one day being able to mine is not an authorized use. See 43 C .F.R. § 3715. These regulations support the conclusion reached by the magistrate judge and the district judge: in order to lawfully occupy public lands for mining purposes, one must actually mine. Willison was not entitled to remain there on the theory that he might someday be able to resume his mining operations.

C. Presumption of Innocence

Finally, the fact that the magistrate judge neglected to instruct the jury on the presumption of innocence at the close of all evidence does not warrant reversal. Because Willison did not request such an instruction or in any way point out the magistrate’s oversight, we review his claim for plain error. See, e.g., United States v. Payne, 944 F.2d 1458, 1463 (9th Cir.1991).

The failure of a court to specifically instruct the jury that a defendant is entitled to a presumption of innocence will not be considered plain error where “ ‘the record supports a sense that the jury was aware of the presumption of innocence.’ ” *619 United, States v. Garcia-Guizar, 160 F.3d 511, 524 (9th Cir.1998) (quoting Payne, 944 F.2d at 1467 ). In this case, defense counsel repeatedly referred to the presumption of innocence when questioning prospective jurors, and the judge himself also mentioned it once during voir dire proceedings. In his opening statement, defense counsel again reminded the jury that Willison was to be presumed innocent. Thus, the record fully supports the conclusion that the jury was adequately informed of the presumption of innocence.

AFFIRMED.
