Manager Working with the Roadium for almost a decade I can confirm that The Roadium is filled with treasures. I surf, snowboard, am intertwined with technology, surround myself with nature, practice yoga, appreciate discounts, people watch, play ice hockey, read books in hammocks, and a list of other things. And for all the activities I pass time with, I have found at least one deal on an item that has made that past times even better. When strolling around the park I always see something that I didn't know I needed until that moment.
