AC 1303 and AC 2507 for CH 223

This (cheesy!) video will give you a glimpse as to what our two main CH 223 classrooms (namely AC 1303 and AC 2507) look like at Mt. Hood Community College in Gresham, Oregon, USA. Some of you have not been on the MHCC campus before, so here is a virtual method to "see" it!

To get to both of these classrooms, go to the "F" or "G" parking lots (or as close to them as possible), both of which are near the main MHCC entrance on NE 29th street and NE Kane Dr. in Gresham ). AC 1303 is on the lower level of the campus, adjacent to the Planetarium. AC 2507 is on the upper level of campus, and it's very close to the "F" parking lot.

Looking forward to a great term with you, and let me know if you have any questions! Peace!
