None but the brave enter.
None but the soul searching for independence enter.
None but the hearty, faithful, and patient enter.
None but the unswerving, mettlesome, insane, nutty, overbold, and, yes, even the impetuous enter.
The roads and freeways are clogged with these emboldened and encouraged souls entombed in air conditioning and swirling (depending on the time of year, that is) heat.
