Travel
To get to Livermore, it's best by car - please let me know if you are trying to carpool from SF or LA or the airport.
From Oakland and SFO you can take BART (train) to Pleasanton / Dublin Station and then uber 15 min from there OR uber directly from any airport OR renting a car might suit you best.
