Cherie has been a full-time technomad since 2007 joining up with her partner-in-crime Chris, and is currently splitting time exploring North America by boat and RV. Growing up in a high tech household, she was using the internet since before it was called the internet. She absolutely needed reliable connectivity to take her software development business on the road in 2007 to work remotely. After answering so many questions about mobile internet on their Technomadia blog (view their personal Mobile Internet Setup) we set out to create the Mobile Internet Resource Center to help the nomadic community stay connected.
