I would think that these lessons would not qualify as a "school sponsored event" so carry would be legal outside, as long as the school is not having their own soccer practice... Unless the group putting on my kid's lessons would be considered an "educational institution"...
What say the legal scholars in here?
Relevant code (really wish it would have been better defined this year...):
Sec. 46.03. PLACES WEAPONS PROHIBITED. (a) A person commits an offense if the person intentionally, knowingly, or recklessly possesses or goes with a firearm, illegal knife, club, or prohibited weapon listed in Section 46.05(a):
(1) on the physical premises of a school or educational institution, any grounds or building on which an activity sponsored by a school or educational institution is being conducted, or a passenger transportation vehicle of a school or educational institution, whether the school or educational institution is public or private
