Not working? There is a bug at Google that sometimes creates an unsolvable reCaptcha when viewing the Calendar from an iOS device like an iPhone or iPad on the Safari browser. We can’t fix it, but you can work around it by either going to Settings –> Safari and turning off “Prevent Cross-Site Tracking” or by using this link instead: HCFF Calendar. Use the Contact Us form to let us know if you continue to have problems. Thanks.
