Well A. Dont take it to school. Wake and bake, run back to your house if you gotta, wait till after, either way theres no reason to risk it.
...butttt i wont lie ive done it before, I actually had a way to do it in the school regularly. It wasnt worth it in the end though, i ended up stashing a piece cause i heard they were searching and they didnt anyways but it wasnt worth it.
If you do, keep it on you at all costs, the dogs are meant for parkinglot and lockers (thats the only places the school has the right to search consent searches to). Ive had chances to talk to one such kid however while he was holding and the dogs were running through and he made out without a search. Though they technically have the right b/c dogs they are still reserved about using it.
