If you've ever adopted a feline or canine friend, you know how important animal shelters are. So here's your opportunity to help out those animals that haven't found a home yet. The Pasadena Humane Society's goal for its annual walk is to raise $325,000, which will help provide for its inhabitants, as it costs $25 a day per animal. All you need are your walking shoes—dogs optional—and maybe some friends/family, and you're ready to embark on either a 3.2-mile route or 1-mile loop around the Rose Bowl. The event is free, but the PHS encourages you to start a team or find sponsors to raise funds. Afterwards, you can look forward to photo ops and pet-friendly booths, not to mention local food trucks (there's no doubt you'll work up an appetite!). If you can't make it, you can still donate here.
