Last year, we spent some time chatting with the Higham family – a rocket scientist, his wife and their two kids, who spent a year traveling around the world. Now they’ve got a book out about their wild adventures and lovely experiences – “360 Degrees Longitude: One Family’s Journey Around the World” – and a web site filled with advice, in case you’re contemplating an extended trip with your kids. And they’re doing talks at various Bay Area REI stores over the coming weeks:

• Sept. 16 at 7 p.m. at the San Carlos REI

• Sept. 22 at 7 p.m. at the Saratoga REI
• Sept. 29 at 7 p.m. at the Marina REI
• Oct. 27 at 7 p.m. at the Berkeley REI
