I'd love to try those sites due to them being just a short drive away but I can't find any information about exactly where and when to go to get involved as a newby. I'm a confident person but going into a completely new environment and not even knowing what to wear is a bit daunting.
Hey mate, Welcome!
We have all been there lol, finding info, wondering what to wear, what to do when you arrive. etc.
It does seem daunting but honestly? You will forget you are a new guy pretty quick, airsoft players are generally incredibly friendly towards each other, and towards new players. Everyone is there for a common reason, to shoot people and enjoy themselves lol.
It's incredibly easy to arrive at a site and start chatting to people, introduce yourself as new and soon enough people will start talking, and it only gets easier as you gain knowledge and experience yourself.
If you are running out of things to say, get talking to people about gear and guns (sterotypical noob questions BUT by far the most effective lol) every player loves their gun and can easily ramble on about why it's good and why you should get one! XD
As for what to wear?
Some good quality boots with ankle support is vital for woodlands and recommended for CQB.
And long sleeves.
Other than that, arrive in whatever you want, the easier it is to wash afterwards the better imo. There will always be players and new guys on site in jeans and hoodies and jackets and such, not everyone is in camo, nor is it required for a regular skirmish!
I will never forget my first time, got to the site, absolutely terrified by the amount of people and their gear, I'm terrible at conversation as well. I was sitting in the safezone with my hire gun, and a regular player next to me said "oh hey, are you new here?" and I said "yeah, first time trying airsoft"
All of a sudden I was lost in the middle of the woodlands map firing bbs at other people and having a great time lol.
