This pair of ad boards can be found in the Powell BART Station in San Francisco. It’s one of 16 pairs (I think I counted 32 total). The “Mother Lode” one isn’t what caught my attention—naturally, seeing 32 of these babies was what originally caught my attention. I think it’s my inner science geek but the [Au]SOME is truly AWESOME! :) I always enjoy Chipotle ads when I see them. Their ad guys do good work!
