Finding sea glass is my favorite part of beachcombing. My small collection has white, green, brown, and blue frosty pieces from east and west coasts. Many these little beauties originate from garbage piles, from a time when the ocean was the town dump (this behavior persists: in one day last year, volunteers collected 168,849 glass bottles from American beaches). Expert sea glass collectors often keep their favorite locations secret, but there are characteristics and times of year to look out for. Old seaport towns and resorts, very low tides. One collector has her husband look up historical records for old dumping sites. My favorite, and one of the more famous locations, Glass Beach in Fort Bragg, CA is now a State Park and gathering is no longer permitted, though I will venture a guess that it is still practiced.
