Heidi Connal is Pat and Heather's sister. She lives in Manhattan, works in New York, but can frequently be found in the oddest places (like Antartica, left). I could go on, but luckily, he has her own web site.
The site details the trip she and her late husband Jon took around the world and offers an extensive travelog with daily entries and photos that really have to be seen to be believed. I recommend the section on Tibet and her continuing relations with Braile Without Borders.
