I lived in the Phoenix area for the last 6 years. Believe me, flats are a way of life there, with or without Slime....road or MTB. Until we moved there I got about maybe two flats a year total. I can tell you without question I patched at least 30 to 40 times in those years out there. At $3 bucks a pop that's a lot of money to spend on something that will go flat shortly. Hence I patched twice and threw the tube out.
