If you want to do something fun and safe this weekend take our VoiceMap Driving tour...start at Home Depot and we'll guide you step by step down del Monte to the Adobes, Fishermans Wharf, the Presidio and then through Cannery Row to the Aquarium...Quick stories that bring it all to life as you travel...I like the fact that you go at your own speed, pausing and resuming as you go..the tour takes 75 minutes but you can make it last all day with so...
