Replying to Weed

To start things off, I'm not a huge smoker just every weekend with my friends (which i don't think is a lot) its just a good time as most of you on this site know! I haven't been smoking for too long maybe 8 to 10 months (which to some of you i still maybe a noob, but thats okay im fine with that)... But sadly i was almost caught by the cops once while smoking in my friends car one night, its a long story that i do not feel like typing and my friends and i lied threw our teeth to get out of it... No names were taken we got away clean

So basically i am asking...
What are good pointers and tips on hiding your shit?
what to do?
what not to do?
Where are good places? (obviously depends on your area, but still)

Before i was almost caught, it seemed way to easy to smoke and i didn't even think about getting caught, but i have to say the whole experiance change my thoughts about it, so now i am a lot more careful about smoking. And and some cases i am almost glad i happen because i got away clean and now being careful abut smoking is just a daily habit that i follow

Oh and i am 16 btw and thanks in advanced
