These Colorado sweepstakes are either just for residents or are limited to a group of states that includes Colorado. Sweepstakes that are of local interest are also included and noted as such. For example, if the prize is a pair of tickets for an event and no transportation is included, even if this is open to the whole country, only local people will have interest in winning this prize. Entering sweepstakes and contests that are limited to residents of one state or a smaller group of states will increase your odds of winning, compared to large ones that are open to residents of the entire United States (or even beyond).
