In which state is the college that Charles attends?
SELECT T1.state FROM college AS T1 JOIN tryout AS T2 ON T1.cname = T2.cname JOIN player AS T3 ON T2.pid = T3.pid WHERE T3.pname = 'Charles'
SELECT "T1"."state" FROM "college" AS "T1" JOIN "tryout" AS "T2" ON "T1"."cname" = "T2"."cname" JOIN "player" AS "T3" ON "T2"."pid" = "T3"."pid" AND "T3"."pname" = 'Charles'
