I'm also torn! Willamette was originally my first choice, but now that I got into Gonzaga I'm seriously considering it. Here are my basic pros and cons.
closer to family/friends (for me)
not far from Portland
law & government program, close ties with the capitol offices, easy access to government/political externships (I'm interested in politics)
lack of national name recognition
writing program is only one year
slightly lower ranked than Gonzaga
cuts the bottom of the class (a very important consideration - if you have a bad semester, you and your tuition money could be gone)
very small school (something like 2,500 total)... this could be good or bad depending on what you want
bigger, prettier, overall better city than Salem
better weather than Salem (less rain and more sun/bright days)
2 year legal writing program ranked 12th in the nation
national name recognition due to its sports teams
bigger school (around 6,000 total)
huge focus on community (tight-knit school)
only cuts people if they actually fail out... not because they're at the bottom
and... I have a feeling Gonzaga will be moving up in the ranks of law schools (Willamette may not)
further from family/friends (Spokane is an 8-hour drive as opposed to 2.5 hours for Salem)
not as easy to get government/political law experience because it isn't near the capital
That's about it for me! I know that everyone has different ideas about what they're looking for, but right now I'm about 65% Gonzaga and 35% Willamette (assuming I get off the waitlist there, which I think I can... eventually).
Let's keep this thread going... there has to be other people torn as well.
