Area 51
Access to Area 51 remains categorically prohibited to all but those possessing appropriate security clearances, typically ranging from Top Secret to levels whose very names remain classified. The perimeter extends 23 miles from the nearest public road, monitored by ground sensors, cameras, and security personnel authorised to use lethal force.
Civilian attempts to approach have resulted in fines exceeding $1,000 and potential imprisonment. Even the airspace above constitutes restricted zone R-4808N, rendering aerial observation impossible without military permission. The facility represents perhaps the most aggressively inaccessible location in the Western hemisphere.
Rubber Duck
The rubber duck maintains exceptional accessibility metrics across virtually all demographics. Specimens can be acquired at approximately 2.3 million retail locations worldwide, with prices beginning at $0.50 and rarely exceeding $15 for standard models.
No background check, security clearance, or governmental approval is required for acquisition. The duck may be transported across international borders without declaration, stored indefinitely without special conditions, and disposed of through conventional municipal waste systems. This represents a democratisation of access that few objects of comparable cultural significance have achieved.
