Does anyone have an answer for this scenario. I haven't bought a fishing license in the last one to two years. I would like to get back into fishing, especially for perch. I have the last week of March off for Spring Break. If I bought my 2018-2019 fishing license on March 23rd, could I start fishing then, or do I have to wait until April 1st. I was wondering if there is any grace period. Remember, I do not have a 2017-2018 license.
