Present for my mates' 21st

[Mike Gayner]

Howdy folks, two of my mates have a joint 21st party coming up and me and some mates are trying to think of a good gift for them. Because they are both adventurous types we thought it would be cool to get them something like a voucher each for white water rafting or jet boating or something similar. Last month we got another friend of mine a skydiving voucher so that one is out, as we want something original. We have already looked at white water rafting, 4x4 driving, jet boating and bungey jumping, anyone else got any cool ideas? The party is in 2 weeks so it's not a massive hurry, but we would like to keep the costs down below around $250 for both of them if possible, as there are only 4 of us chipping in and we're all very poor :nutsycuck
