I feel guilty, sometimes, looking at all these priceless photo threads, and not being charged for it!
Tehran I can relate to, it's a desert city like Las Vegas, surrounding by denuded mountains, except the mountains don't come as close to Las Vegas as those in Tehran. Many times, I wish I could just play superman and move the Spring Mountains closer to town!
Here, the mountains are snow-capped, mostly at the very peaks, for about 6 months a year, but Tehran must have a higher elevation as the snowline comes down much furthur, and even some snow in the city! Las Vegas occasionally, gets a little snow in the city, but rarely!
I also noticed, comparing Tehran to other European City Photo threads, the lack of grafitti, which surprises me, given the political climate there, dissatisfaction, that there might be grafitti plastered everywhere! Not so!
I know desert heat too well, and areas of low humidity, so I'm sure their winters at night can be severe, and even if it hits 100 in summer, like most desert regions, you have a nice cool-off at night. For that reason, I wouldn't hesitate to visit Tehran in the summertime.
Thanks a zillion for the photo tour of a city I've been long curious about!
