1. Your newbie status.
I am definitely a newbie… Started serious whistling last November.
I will do two places here - for amusement sake…
2. The best place you whistled this summer.
In my garden. Its peaceful (when I am not playing
), surrounded by nature with the forest on one side and views towards Wales on t’other. On a good day you can see the Black Mountains, on a bad day you can see my grumpy neighbour 
3. How good the acoustics were.
Neutral (until the wind blows)
4. Did you play by yourself or with other people.
By myself
5. What song/s you played.
(a) Lots - I like ‘An raibh tu ag an gcarraig’, ‘An Speic Seoigheach’, ‘Lamment For Staker Wallace’, ‘Lamment For The Wild Geese’ amongst others.
6. If people were present, the approximate number.
Few or none. Sometimes the dogs, sometimes the neighbours.
7. How did the people respond?
Dogs ignore me, grumpy neighbour looks miserable and goes indoors.
2. The best place you whistled this summer.
A very local pub - at a session!
3. How good the acoustics were.
Just like a pub
4. Did you play by yourself or with other people.
With others
5. What song/s you played.
‘Stanns Reel’ too often and ‘too much like a hornpipe’. A couple of hornpipes (which I muffed, but at least they didnt sound like Stanns Reel). Fanny Power which worked better (these were on different days).
6. If people were present, the approximate number.
4-8 Session players iirc, maybe a dozen innocent bystanders (and once my grumpy neighbour going for a quiet drink to get away from that annoying whistle next door
)
7. How did the people respond?
The session guys were very tolerant (respect is due to them) and they even made some supportive comments. My grumpy neighbour looked even grumpier
