Visitors, faculty, and students alike will always have trouble finding a parking space. The exception is when lucky faculty members spend large sums of money to purchase reserved spots (this option is only available to faculty and staff). Parking is the biggest complaint on the ISU campus. Street parking is students' best option since it is free for 24 hours and not too far from campus, but spots fill up quickly in the morning and stay in use until late at night.
There are also metered spots that students can park in, but since they are hourly and some classes last 75 minutes, students risk getting a parking ticket or spending a lot of money for the meter. If students purchase a permit, they are allowed to park in certain lots coordinated by color; student lots are green and faculty lots are red. The ISU Police are very strict and will not hesitate to give parking tickets. And beware: parking tickets add up, and by the end of the semester, students will not be able to register for classes if they have outstanding fines.
