Fundraising for a specific individual is not considered to be charitable fundraising, since the public at large does not benefit. Therefore, fundraising for a specified individual is not subject to the registration and filing requirements imposed on charitable organizations.
The Hike: Westcave Preserve is a small piece of land owned by the Lower Colorado River Authority. What it lacks in acreage it makes up in scenery. This little brother to nearby Hamilton Pool offers some of the same formations, and some unique ones, and does so with far fewer crowds.
Getting there: From Austin head west on Hwy 71. Turn left onto RR 3238 (Hamilton Pool Road). Head south for a bit over 14 miles to the Pedernales River. The entrance to Westcave Preserve is the first gate on the right after crossing the river.
