Travel

Autumn is nice and cool - very suitable for travelling. I need to make a detailed plan before any journey - plans such as where to travel, what is the weather is like there. I also need to book air ticket at a low budget price, and book cheap, safe, clean, and quiet accommodation/hotels. My mother usually says it is not safe for a girl to travel alone. I want to buy some local specialties to share with my family and friends when I come back.

Nice photo and entry!

(1) alternative option. Autumn is nice, cool, and very suitable for traveling(American English it traveling, British English travelling)

 (2)If asking a question What is the weather like there? would be correct in this case it´s more rhetorical.

(3) need + infinitive Example I need to go to the store. I need to buy a ticket I need to walk the dog.

(4)A singular object... ticket, hotel room, car   we put¨a¨ or ¨an¨ in front of the singualar object.

(5)present tense... a habit regular activity, habit etc... we use says instead of the past tense said.

(6) souvenirs = small gifts you buy when you visit a country like keychains, pens with the country name written on it, etc.

Great post! Enjoy your travels.

Did you mean "specialties" instead of "speciaties". A souvenir and a specialty are essentially the same thing.

Very good work! You have a great sense of grammar and punctuation. Be proud and continue learning! :-)
