I don't mind walking 15 to 20 minutes to where I need to be in downtown Denver, but it'll be useful to find some free street parking, during the evening time, 21:00/03:00 MT.
Any such thing in Denver, Colorado, the USA?
For many years prior to March 2011, you could park for free on the streets in downtown Denver, from 22:00 until 02:00, but there was no street parking between 02:00 and 06:00 (supposedly for street sweeping). Almost every single web-resource you find nowadays, two years later (April/May 2013), still insists that parking between 22:00 and 02:00 is free, but that you always have to leave by 02:00; not the case at all.
Since about mid 2011, street parking between 22:00 and 02:00 is no longer free, but is 1$/h, and 0.50$/h between 02:00 and 06:00, and free between 06:00 and 08:00; the smart meters take credit cards. (Street sweeping takes place on different days for different streets, such that overnight parking is always possible.) The exception is Sunday: after 23:59 on Saturday, you can park for free for a number of hours, on all city streets.
