Johamna, your photos are amazing. I had to sell all my DSLR stuff a few years ago to save for deposit on a house.
I've never really missed it until seeing your pics and now wanting a DSLR for my trip to Florida end of April.
What camera / lens are you using for those images?
What time are they taken in the park, looking at what hours the parks are open at night to decide where to go and when.
