I'm assuming you already have info on Alabama shows and are looking for more...but if you don't, Chambers County's show is back on (late May) and Pike's show is in mid June. The AJCA Round-Up in Montgomery is also great (late July). Coffee County Invitational (early August) and Henry County (early September).
aces.edu/~rebert has a full list. Round-Up info is at bamabeef.org, go to junior cattleman, click on roundup link.
