Texas has this little out of touch with reality commission called the Texas Antiquities Commission, formed out of the Texas Ant. Act of 1968. The state claims everything on public property is the property of Texas. The Beaches of Texas belong to the citizens, so all beachs NOT part of a State or National Park are OK. Almost all County Parks around any place that has any historical significance at all is off-limits because of the twidgett bean counters in the bureaucracy. Harris County, Houston area, is also off limits. Not because of any possibility of something really OMG about history, but some little a-hole that has a very high regard for their own self importance might just see someone taking something, like a nickle or a ring. The County doenst have the money to defend or investigate every report, so they do the cheapest and unlawfully take public property rights.
