As with all plein air painting there are challenges to consider, like location, safety, shelter from elements, or traffic? Is it safe to park and set up your easel in a new area? Is there sufficient shade shelter to protect you from the sun or unexpected shower? How much street traffic can have a major impact on the ability to start let alone finish a painting on-site. Is there a decent spot to stand without disturbing any unwanted pests like fire ants or wasps?
