I'm a virgin looking forward to my first burn this year. I'm flying from Europe for this occasion to San Francisco.
My question is about the Burning Express :
I've seen that the BE doesn't make a grocery stop if it comes from San Francisco.
What would be the most easy ? either :


Also, is it easy to find a cheap second hand bike in San Francisco or in Reno, a few days/weeks before the Burning man ? I'm guessing I'm not the only one trying to buy a bike.
Thank you all for your help, looking forward to meeting you on the Playa !
