Best crack in town
Watch out for creeps that may or may not sexually harass others. Call it out if you see it for the sake of others' dignity and sanity. Good space for transit to other centers and just to get around.
Under renovation right now but should look really good when finished. Pay attention because locations of stops change all of time because of construction.
One dollar 20 ounce sodas can't be beat downtown
It's yucky. Hang out for more than a couple of minutes and you'll smell like smoke (possibly weed smoke), get panhandled at least once and figure out what's wrong with the youth of America.
Best place in Arizona to hookup.
The loud music is annoying. Hard to tune out.
Despite what the previous tip stated it is perfectly safe downtown. Ronstatdt is a great place to visit. It is a gateway to explore all the culture that is available downtown.
Catch almost any bus from here! Near train station and downtown hot spots. Place is kind of a hang out for people who seem to be up to no good. No real danger, but I still like to get my bus and go.
