the past 20 years we have had alot of rain..so the desert is overgrown with every kind of bush and shrubbery imaginableDave , I agree . Everything in this world changes every day . I saw paths which in few years became inaccesible because the brush and weed . Sometimes I couldn't recognize a region after a decade . Imagine how different would be a region in the wilds after 100 years . Totally different .
