God Jul from Petersburg!

Little Norway is enjoying lots of snow this holiday season and the mountain tops and forests are enchanting vistas. Toni and I have been spending time in Oregon and we are pleased to announce the arrival of a new granddaughter! Arden Iris Rogers arrived early on the morning of December 3rd. A wonderful Christmas gift indeed!

In our ongoing effort to support global travel, we are pleased to announce that Alaska Sea Adventures will be joining Cheeseman’s Ecology Safaris on their February 2023 cruise, Whales, Penguins and Golden Landscapes. For additional information, contact Cheeseman’s and mention that you are traveling with ASA or contact Captain Dennis.

A Family Testimonial from the Summer 2020!

How could we be so unbelievably BLESSED to have experienced this voyage on NS amid such a crazy time?  If you have to quarantine, this is for sure the place to do it! We have all been in awe of this amazing crew-top of the line knowledge, experience, warmth, generosity, talent! From start to finish we could ask for nothing more, except perhaps more time…
