Public transport in Dallas exists and is somewhat accessible (bus connection about ½ mile away), but it is not advisable to rely solely on this for getting places locally (i.e. church, grocery store, home off-campus, etc). A bicycle, at least, is recommended. You can rent an automobile by the day through the SIL housing office (firstname.lastname@example.org or 972-708-7426). To investigate buying an automobile, contact email@example.com for help and advice.
