I'm legal! I can now hike in the Bull Creek Preserve from March through August, during the golden cheeked warbler and black capped vireo nesting season. Both are endangered species. Not likely to see one though; usually only one pair nest per 5-acre parcel. The preserve covers 30,000 acres, surrounded by the City of Austin.

Old cedar stump. The forest has gone through two or three cuttings. Central Texas cedar trees were used for railroad ties across the nation decades ago.

Papa Tom, at a limestone escarpment estimated to be 70-80 million years old. Endangered salamanders live in the holes in the limestone.

Bull Creek. This is a rather special place for our family. Ryder and Brandy had their first date at the Bull Creek dog park. Marley was there too. And the rest, as they say, is history.
