Not sure if it is okay to ask this, but my father used to drive long haul out of L.A. and it occurred to me this may be a solution to my dilemma. I am a single mom, and can not afford to return to Northern California for my son's high school graduation this coming June. At least not in a traditional manner. As it stands, my plan is to walk from my home here in Michigan beginning in February (averaging 20 miles per day), in order to make it on time. My question is, since my physical health is questionable and the weather and terrain will be tough, at least in the winter months, how likely would it be for me to possibly catch a ride with someone hauling west for parts of my journey and is there anything other than common sense I should know if I should be offered a ride?
