Add a new rule to the ruleset, called Attraction Seed:

Once in the dynasty, at their earliest convenience, the GPS must carry out the following atomic action:

*Generate three Attraction Stops, as per the rule Roadside Attractions, without appending them to the list of Stops;
*Randomly select three numbers between 19 and 29;
*Insert the newly generated Attraction Stops into the list of Stops, each immediately after the Stop at one of the numerical positions generated in the second step of this action, in the order in which they were generated, and then renumbering the list accordingly;
*Repeal this rule.
