Small Rural Lot in Austin, Texas For Sale

Looking for a small rural lot to put a trailer or cabin for weekend home and to use during hurricane season as an "evacuation" destination. Am retired and on a fixed income so cant be too much, hopefully 1 or $xxxx, but will consider other offers. It would be nice to have a small pond or be by a creek or river. Email is best way to contact right now.
Thanks, we are hopeful to get something this Hurricane season.
