It may be a hint of things to come, so if you don’t already have a waterproof backpack or pannier set up, consider something from Ortlieb or Freight Baggage. Whether you need something for books, the occasional groceries, or a legal copy box, these two companies get our vote for function when conditions turn nasty. The Ortlieb products are all guaranteed water proof unless you carve an anarchy star in it ala Bud “brooks saddle” Durand’s. (which by the way is still waterproof)
