 To make room for the expected flood of visitors' cars on Gibraltar's crowded roads, 1,000 old vehicles were rounded up and pushed off the cliffs into the sea at Europa Point at the southern tip of the territory.Despite this drastic measure, parking spaces were in critically short supply as over 1,000 vehicles per day entered Gibraltar after the reopening of the border.The territory enjoyed a retail, accommodation and catering boom, though it came at the price of chronic traffic problems and threats to the environment, notably disturbances to the macaque and bird populations.
