definitely a good idea mate. I've two kids, 2 and 4 and have been working two jobs the last few years as I thought i had the time and the money was to good to turn down (Fireman and Roofer) but realised in the last 9 months actually i really dont, i work between 70 and 90 hours a week..........oops
So i thought about needing to get a hobby back to make time for myself, I saw a giant martin hawyes with mag's a other decent bits and the guy only wanted £60......trials it is then!
I used to ride but got bored about 7 years ago, never actually applied myself, was alright at street but pelt at proper trials moves, Point is get out in a group and it will always be fun. second point is make sure you keep some you time, i love my rugrats to death but its important not to stop being a grown up doing your own grown up things for yourself!
Good luck and enjoy mate!
If you need to buy anything defo use the FS section on here, i've just re-specced my bike apart from wheels mentally cheap for the quality of gear!
