A small group of congressmen is lobbying President Obama to put a little extra in his budget request for the National Park Service so more parks can be "wired" for cellphone and WiFi.

"Since its founding, our National Park Service has set an example for the world to follow, and we believe that investing in 21st century telecommunications infrastructure is critical to maintaining that leadership," reads the letter. "In honor of the Park Service's centennial, Director Jon Jarvis has commited to providing free public WiFi at all park visitor centers by the end of 2016. This is an important step to improving connectivity in park units. However, additional resources will be necessary to continue this momentum into future years."

The letter (attached below), sent on Wednesday, was signed by Rep. Jared Huffman, D-Calif., Raul Grijalva, D-Ariz., Niki Tsongas, D-Mass., Derek Kilmer, D-Wash., and Jared Polis, D-Colo.

The five voiced their belief that expanding WiFi signals in the National Park System would help attract a more diverse audience of visitors.

"... improved connectivity will help to make our parks accessible and engaging to changing park visitor demographics," they wrote. "It will also support the Park Service's long-term goals of improving public safety, providing greaer interpretive services, and meeting the needs of the visiting public."
