Odiham - yes, been there and it was fun. Apart from a blustery day when I was a student I flew in there with an instructor.
ATC were excellent and even showed us round. My landing was ok-ish but ended up taxying for ages along the RWY! The ATC chappy politely suggested that I didn't need to use the entire RWY for take off and I did as he said, probably using no more than 10% of it.
Good fun and I recommend it.
