I am fat and slow -- but at 43 , not quite old yet but not quite young either --- but DST has got me excited as well ---
I look forward to re-purposing some of the older iron i brought home this winter into a commuter
I am a bit geographically challenged though as i live on an acreage outside of town --- just going to town turns into a serious ride and a bit white knuckle due to narrow, heavilly trafficked roads ---- so a commuter build is useless to me, but i like tinkering with cool stuff.
The combination of i-phone texting women and beered up trailer park dwellers driving dually pickups in my area means i even truck my road bike to a nearby lake to do laps on the lake road in relative safety ---
--- given the land i am sitting on though , i am fleshing out ideas for a pump track in my backyard , as i recently aquired a retro style SE bmx cruiser, -- would be a decent place to give a hardtail mountain bike a workout too i hope (I have also re-aquired an interest in classic BMX stuff too - i may share here if i build something nice -- this forums bmx section is woefully lacking for older guys' who like the vintage iron from the late 70's and early 80's )
But until my pump track dreams come to fruition, i will turn laps occasionally at the local bmx track
Doesnt this look like a fun place to play ride? The riding style popular today in bmx is to wheelie (or manual) over the jumps rather than catching air, -- so it is much more forgiving for guys' like me who dont have a lot of skill in that area
--- Another neat thing is i took along my heart rate monitor , -- 1 lap gets me to 165 heart rate --- so in essence, i am doing intervals while i play ride
The bike is retro styled with 26" wheels --- it still has a V-brake and a threadless stem, but the geometry is very similar to what was used in the 70's --- compared to today's BMX cruisers which are long and low with much steeper head tubes --- and typically alloy frames and in some cases, even carbon fiber

boggles my mind to see carbon bmx er's
I want to find a genuine late 70's /early 80's 26" cruiser to do a period correct build on this year while i continue to bash on the new imitator
It may not be for everybody, but i have found it a fun and refreshing way to keep doing what i love -- which is riding bikes of all shapes and sizes
