We went during their "Zoo Boo Days" but have been many times before that. This is a great zoo to spend the entire day. A little expensive but they do have coupons on line to print out and there is also a discount for AAA members (just show your card and save $2 per ticket). There is also a calendar on the web site that I check often, as there are specials on certain days (moms free on mothers day), (Dads free on fathers day) etc.. It is also cheaper to bring a cooler with drinks and lunch. There are picnic tables inside to sit on and have lunch. When you are there make sure to visit the deer forest which is the highlight of the day. Bring extra quarters with you as there is a corn machine to feed the deer. The deer will only approach you if you have the corn. Also new this year is the parakeet experience, where you can feed the parakeets! This was great. Make sure you buy the food ($1.00) so the parakeets will land on your hand. My son who is 4 1/2 really enjoyed this. Another big hit with my son is the "Crazy" monkey, known to some as the "Naughty" monkey. We visit yearly and always have a great time!!
