They don't say "Keep Portland Weird" for nothing! This town full of original art, friendly folks and environmentally conscious partisans, also has the largest floatation center in the West Coast. Growing in numbers, these centers allow floaters the chance to get rid of all sensory outputs by floating in body-temperature high-concentrated salt water.
Hipsters, hippies and skeptics alike reap the benefits of these new age centers from their first to second visit. Silent Spectrum is a short documentary that explores two of these float centers (and their clients) in Portland, Oregon.
