This "mad lib" will email you a link to a Google Doc of a trail writeup. Edit it as you like, share it with your co-hares for review, and when you're ready: Either share the Google Doc with the Hare Raiser or copy and paste everything into a message or email.
You shouldn't need a Google Account to do this, but you do need to put in an email address to receive the Google Doc. A Google account will enable auto-saving of your entries though.
