I'm currently at the beach and enjoying summer very much, so this should be an easy one!
1) Ocean, lake, pond, or river - get yourself to some water and jump in when the sun is hot!
4) Reading in the shade
6) Fresh lemonade or limeade
7) Catching up on my favorite TV shows (I love reruns and DVDs)
8) Ice cream in the middle of the afternoon
9) Cold soups
10) Getting up to see the sunrise, then going to back to bed for an hour or two
