I saw your message about your Aunt. (Mine climbed the Himalayas I found out at her funeral!!)
You may be able to contact people who are organising this year's swim if you use the email address in the original article and ask for it to be forwarded to Madeline Willis. http://www.outdoorswimmingsociety.co....php?p=news&s=
If the link doesn't work, go to the Outdoor swimming soc and click News.
There is quite a lot to do in Perthshire. Try www.perthshire.co.uk for ideas.
Things to think about might be high or low ropes, cycling, abseiling, spheres, climbing or quad biking.
Hope the holiday goes well for you......
