What is the best way to randomly choose these 500 people?

Select the first 500 taxpayers listed at the town hall.

Choose 100 taxpayers from 5 different age groups in town.

Survey the first 500 people who visit the existing skate park.

Assign each taxpayer in town a number and then randomly select 500 of these numbers.
