You CAN do it!
Yesterday my youngest and I went to the zoo...I don't think I"ve ever gone to the zoo with JUST her before...We had a wonderful time!
Now, when I go to the zoo by myself with my kiddos, I don't bring my DSLR camera...I'm pretty much addicted to it and I know this about myself. I know it so well because I tend to loose track of anything that doesn't fall in front of my lens as I'm looking through it...I've been known to "misplace" my 2 year old because I'm focusing on some flower and blurring the background while fiddling with my aperature setting...
Where did she go? Oh, about 2 houses down chasing after a squirrel??
Yes, so...when I go to large places without another adult present to aid me in my "lack of paying attention" issues, I just bring my little cybershot point and shoot camera. It's a learning curve for me because I'm used to lots of buttons and sometimes I get frustrated because I wonder if I'll be able to get the shots I envision with a little camera...
I want to offer encouragement out there...you CAN get good shots...even with a little digital point an shoot. You may not have all the range of creativity that you might hope for...but with a little practice, a good eye and perhaps little photoshop processing, you can get some good photojournalistic images! These were all taken with my little point and shoot camera...
