The 7-11 is off Osbourne on the 210 freeway, close to where it meets the 118. Across the freeway from the Hanson Dam Recreation area. Get off the 210 and head North towards the hills and turn left at the signal, The 7-11 is semi hidden and will be on your left. No more than 1/4 from the freeway.
Have a good ride...it's spend the day with the wife for me.
