I recently moved to okc from Texas. I know there's some interoperability, and that Toll Tags are accepted. However, I have a TxTag, similar to a toll tag, but put out by TxDot.
Topaz is commonly used for Friendship Rings and it is nicknamed 'the gem of friendship'. Topaz is considered in some cultures to be the ultimate representation of friendship and fidelity.
The Friendship was built in 1784 at Scarborough and was a brig with a burthen of 278 tons. On her return voyage to England, in company with the Alexander, her crew was so badly affected by scurvy that the decision was made, on 28 October 1788, to scuttle the Friendship off the coast of Borneo.
