Hey,
Well they are not exactly traveling a lot right now but I have a very good feeling they will be soon.
THey are just five specific numbers that have hit a couple of times in multiple states last year in 2010 and I think will continue to run hot this year. As you can see the 3076 Traveled from New Jersey to Tennessee on 4/19/11 as NJ got 3076 Midday followed by Tennessee getting 6370 for the Evening both on 4/19/11!Also Maine got 2947 BOX on 4/20/11 Evening and then Ohio got 7924 BOX on 4/21/11 and now Virginia gets 2974 BOX on on 4/23/11 Evening. So the 4972 BOX is an excellent example of a Traveling number. This pattern of the same boxed number hitting multiple times throughout different states is what makes a number hot or a good "traveler".I reccomend you play all of them boxed but I also listed them in the order I think would be best to play straight.
Also the 3107 has already hit box in a couple of states this year and hit many times last year in 2010 and it's just one of those numbers I think would be a good traveler for all states.
I basically just listed the five numbers that I think would be the best repeating numbers that will hit in multiple states so thats why I named them traveling numbers because I think these five will continue to hit in many states. Best of luck to you if you decide to give some of them a shot!
