Wear comfortable clothing and especially comfortable shoes. Talladega is so big that you will be walking A LOT! Because of all the camping and smoke here on race day it is usually warm so t-shirts are usually your best bet in April or October. Never been to a race at Talladega when it is cold. As for rain, bring a poncho cause Talladega does not allow umbrellas inside the track and the gift shops don't offer weather gear. Also remember that if there is a rain delay you'll be in a rain delay for awhile since it takes so long for the track to dry and the parking at Talladega is dirt pretty much so if it rains you'll be walking in a lot of mud and bring boots cause you might have to push you car out, it gets that deep.
Camping at Talladega is the best on the NASCAR circuit and can even get wild at times and I would suggest if you go to Talladega to do it at least once. If you camp prepare to get to the track a couple days as it is on forst come first serve basis outside the infield and don't expect to get much sleep cause everyone parties the night before and some even get in beer drinking contests, LOL! Overall, a tent that is enclosed because of the bugs are preferred but any tent, lots of coolers, a grill, and chairs are the necessity.
