The Lacy Park pool, 2134 N. Madison Place, opened on Friday and is offering free admission Saturday. It was supposed to open with the city’s other public pools in June, but problems with the construction work on the $3.2 million project caused delays. The pool now has dual slides, a rock climbing wall, a zero-depth entry with play features for kids, and a 12-foot deep end with a diving board. Hours are 10 a.m-4 p.m. Thursday through Saturday.
