This week, Jeremy and Dave travel along Interstate 70 through Colorado, crossing mountains and canyons, not to mention looking for hidden secrets in the city of Denver. Jeremy also gives listeners a sneak peak of his new travel book - The Road Trip Book - Travel America Like You've Always Dreamed, set to debut in bookstores next week. On This Week in Travel, we talk about the sometimes-crazy antics of Russian buses. And in our On the Lighter Side comedy segment, we'll have "Fun With Siri". It's another hour of roadtripping, travel, and fun on this week's edition of Road Trip Radio.
