Read the following context and choose the best option to answer the question.
Context: It 's a domestic day around here , so I thought it might be more fun to relive the best Labor Day weekend ever while I clean up from last week 's fun and prepare for this weekend 's windy wetness . I mentioned my act of bravery the other day , and found in my husband 's pictures the proof - here I am standing at the point of no return ! The parking lot is on the other side of that bridge , and in this photo I ' ve walked over and must soon walk back . All that separates me from a nice , safe , manual 6-cylinder mountain - loving car is a mile - deep chasm and a swinging metal bridge .
